Reciving calls with blocked id!

Not applicable
Hi all, (first post yay)

any way since i got my new 02 number ive been reciving call from a unknown number (blocked cant see the number) almost every day 1 to 3 times per day.

When i pick up the phone there is nothing at all at the other end just silence.

Now i did call support and mention this but all i got in return was the only thing you can do is change number.... umm i think not.

Now i know it is possible to trece these kind of calls due to privacy and criminal laws.

So any suggestions on what i can do ?

PS: have no idea if this is the right place to post this

This is not a easy one. Im affraid you will have to go back to o2 regarding the issue and ask them to investigate further, however this may sound bad, but as o2 have offered to change your number, then this can be classed as a viable option.

There are facilites on mobiles that you can block uknown calls. but this will block any one that has call id with held or puts 141 in front of your number.

There is a website that you can register your mobile. (TPS Telephone pref service) but agian this takes over 28 days months to register in the uk and is really for call centers etc.

If you need anything else please let me know.

There is an Nuisance Call Bureau that O2 can refer you're case to and they should have offered this. It unreasonable to think every customer is willing to just change their number.

Contact O2 again and ask for your case to be referred to the NCB and they will then contact you back within so many working days. ... phonecalls

Hi Thanks for the tips.

i sent a email to o2 suppoert again and all i got back was a template station what has been stated before.

Now i know there can be something done with it without me having to change my number.

Dear O2 Customer,

Thank you for contacting O2 customer service.

O2 appreciate that receiving unwanted calls and messages on your mobile
phone can be cause for concern.

Please use the link below to view advice that has been compiled, in
association with O2's Nuisance Calls Bureau, to help you deal with any
unwanted contacts. Remember malicious callers use the phone to hide
behind, because most would be too frightened to say the same things to
your face and some malicious callers may want nothing more than to have
a conversation.

If after reading this advice you decide that you would like us to help
further, please reply to this e mail or contact customer services. We
may then offer to have your number changed if it is felt that this will
resolve the problem for you. There is no cost for the change of your
number if it is in relation to nuisance calls but we can only offer this
change once.

Alternatively, if a number change has failed in the past or you believe
this will not resolve your case. You should advise us in your response
that you wish to pursue the matter further, so that your details can
then be forwarded to the Nuisance Call Bureau (NCB) for further

Please Note: When you are contacted by the NCB they may require dates
and times of calls/messages and in this case you will be required to
report this matter to the Police.

Please Note: Requests of this nature are currently taking 3 working days
to complete.

Well here is the answer i got this morning. Have to sy im not to pleased.

Guess is have to register with TPS and see if that helps.

Thanks for your help and tips guyes.

Good morning (name removed)

Thanks for emailing us about the nuisance calls you've been receiving. I
understand that since you got your new 02 number you've been receiving
calls from a unknown number (blocked can't see the number) almost one to
three times per day. When you pick up the phone there is nothing at all
at the other end just silence. You were told that you could send this on
to the Nuisance Call Bureau as these calls are getting really annoying.
Let me see what best I can do to help you.

Firstly, I apologise for all the auto-mated you received from us. Yes,
you're right the Nuisance Call Bureau does investigate this matter, but,
this is only after you've changed your mobile number. However, if you
wish to speak to the Nuisance Call Bureau team you can call our friendly
customer services team on 0870 600 3009 who'll transfer your call to our
Nuisance Call Bureau team and they'll be happy to help you. They're
available from:

- Monday to Friday between 8am-9pm
- Saturday and Sunday between 8am-8pm.

Calls to the above mentioned number are free from any O2 mobile and are
chargeable at national rate from any other service providers and fixed
lines. You can also email them at or you can also register
yourself with Telephone Preference Services (TPS). You can email them

This may take up to 40 days to be fully compliant. If this still doesn't
work then you can change your mobile number.

Trust, this helps and once again I'm sorry for all the inconvenience
caused to you. If you should have any further questions, please contact
us or visit our online help centre at:

When you email us please provide: your first line of address and full
name, postcode and mobile number as it helps us answer your query

Kind regards

(name Removed)
O2 Customer Service.

Getting your query right the first time you email us is very important
to us. If your query has not been resolved this time, please reply to

It would be a lot simpler to answer the calls, find out who they are and make a formal complaint against them.

If they are UK companies and you tell them you are registered with the TPS, it's usually a grovelling apology and they don't call again.
