Excessive call charge

[DavidJM]

I've discovered that for the last 3 months that despite my mother and I both having pay monthly contracts with O2 that when she has been calling me she has been being charged for this to a quite considerable amount. No other number she has been calling or anyone else that has called me seems to have been charged. Would anybody have an explanation other than O2 have made a billing mistake

@DavidJM 

The only time you would be charged for making an O2 to O2 call is if you had used all your inclusive tariff minutes.

If this isn't the case for your Mother, I can think of no other reason why.

I can ask @O2Lisa or @Korey01 to look into it for you though.

As far as I'm aware she had unlimited minutes, my sister has checked the bill last night after we discovered the vastly gigher phone bills and only calls to me have been charged for, not anyone else.

Thanks for the tag @MI5 

I'll private message you now @DavidJM so we can look in to this for you

Hope you get a good outcome

Problem seems to have been traced to my mothers account but there has been no explanation from 02 yet for the high call charges. They couldnt solve it on a phone call and have said they need to investigate and will call back.
