Can't pay half of my bill

[10529466580]

Hi, my contract was on my host  first (I'm Ukrainian), when I moved out I started to pay on my own but don't have acess to the other bill. I regularly receive messages about the payment but when I try to acess it on my O2, I'm offered to choose a number endnig in 97 to send the code. But this number is neither mine nor my host's!!! I want to have one account and pay regularly from my debit card. The last message is with the bill 1052946658 payment by 09/09
