My teenage son lives with his Mum but i pay his monthly (contract) phone bill. His data usage has gone sky-high as he has been buying bolt-ons without my consent. I changed my username, password & security question but he still has been able to buy bolt-ons. I think he is doing this through the O2 app. It seems that if you "forget" your log on details they will send you a pin number to access the account - is this correct? If so, then I don't know how I can stop him from buying these bolt-ons, and i suppose he could even upgrade his phone etc. Can anyone help please - I'm at my wits end.
