Dear team,
I have my monthly bills of o2 sim and my iPhone installments have to pay. I have changed main bank account and also changed my bank account for the o2 payment at my a o2 shop but still o2 is trying to take money from my old account and it costs me extra fine. How I can change my bank account in another way. Any help will be much appreciated
Thanks
