I have credit balance on my credit card. When I wanted to transfer the money to my bank account, there was a transfer fee. The amount is much less than my actual balance (my credit balance was -£639 but I wanted to transfer £600 and I am still charged with a transfer fee). I have not made the transfer yet as I do not want to be charged extra.

I tried calling the customer service on 03453004278 but it was just a robot operator and there was no option that I could choose to sort this out.

Any help is very much appreciated.
