Can't receive calls - Can I leave O2

[abbbcccguest]

I can't receive calls with my sim. I've tried resetting the phone, settings, switching phones, and nothing works. It says I have signal, and I can make calls (sometimes). I would like to leave O2 with no extra charges as I'm not receiving the services I'm paying for. I am trying to open a case via ombudsman but need a deadlock letter, however there doesn't seem to be any way of contacting O2. Live chat doesn't work and just says no agents available, and I can't find any email address for customer service. My next option will be to open a small claims court case to claim the money back. I have tried calling but after being on hold for an hour I was hung up on twice.

You need to call customer service.

Call 202 from your mobile or 0344 809 0202, 0800 902 0217 or 0800 032 1402 

If you have no access to a phone then use Skype to call 0800 032 1402 #skype guide

When you call, you will be asked for the reason you are calling,

Stay silent for 15 seconds and you will be taken to the keypad options.

Press 2 for Everything Else

Press 5 for More Options

Press 7 for Anything Else which will put you though to an advisor.

Press Upgrade, Lost/Stolen or Fraud if you have to.

8am is the best time to call

If you want to leave then follow the guidelines here  Guide: Cancelling Your Contract

@abbbcccguest Have you tried replacing your sim? It may be something as simple as that. If you have an O2 store nearby, call in bringing photo ID with you and they'll swap your sim for you there.
