Complete data usage when abroad, but get charged for only one day!

[Malo]

Myself and my wife had been abroad and we used data for one day each, because of the situation.  Obviously we were charged £7.5 extra each.  But, apparently on the day we returned, we were sent a text that we have used all data (both of us), we both have not received it.  Between the date when my monthly data renews / commences and the date of their text, we were not in UK.

We had switiched our mobile data off and roaming off (which we religiously do when we go out of UK / Europe)

Surprising thing is, we were not charged for using all of that data abroad, but only charged £7.5 each for rest of the world usage of data.

What I cannot understand is, if we should be charged £7.5 per day, I do not think we will be exhausing our data which is allowed in UK. Then, when we were not in UK, how did we use all our data?

I tried to get answer via chat, but that person was not able to help much because, they could only see what was on the system, and I do not think they understood my query.

And again this month, I am told that I have used all my data within 14 days which is a bit surprising.

Looks like there some fault with O2's computer system / recognising when we are abroad / within UK or EU, and we are getting charged for no fault of ours.

Hope O2 answers my query,,,,

This is not O2.

You need to contact customer service to investigate Guide: How to find help & contact O2

Hi @Malo , how was your weekend and did you manage to find out more about your data usage abroad since you last posted?
