bank deposit

Dear O2 support team,

I’ve contacted the support line via telephone however the issue wasn’t resolved. On the 31st of July, I made a deposit of 30 euros to the IBAN and BIC of the (Telefonica Germany G) or O2. However I did not add my phone number nor any sort of identification code. Therefore I would like to ask to have the money refunded to my account. I’ve already charged my phone therefore there is no need to fulfill the transaction to my O2 account. I couldn’t solve it over the phone nor know how to contact you guys, therefore I'm sending this message. 

Kind regards
