The mobile phone network withdrawing is automated at the mobile networks side, you payed them another way just a few days before the withdrawal was due so it might have crossed. It would have been wise if you had called your mobile phone network the day you payed them in a different method to inform them that you did so they could cancel the automatic withdrawal. They are still not responsible for any agreement you have with your bank.

In short: If you had notified the mobile phone network before withdrawal time and they still charged then you "might" have a case, but if you did not then there is nothin you can do about it and you can't claim that money back from anyone. Just let this be a lesson on how to handle such in future. And find another bank with no such rediculous rules!
