So my 16 year old is in Florida with her dad. Told her specifically not to make phone calls/send texts etc and told her to switch off her data roaming, which she has done. Checked her account this morning and there are two phone calls to (or from) her dad's phone totalling up to about a tenner. I know it's only a small amount but am fuming as he's done this before whilst on holiday with her and refused to pay for the calls (he pays no maintenance, I pay for her phone and pretty much everything that she has!) I suspect it's him who has made the calls to her phone as she knows not to use it. So I called O2 and had them bar her phone from making or receiving phone calls until I ask them to unbar it! Am I being mean?
