On the 30 the September I requested a settlement balance after the debit order was deducted. Note this is a interest bearing account, so I'm paying interest for every day that there's an amount outstanding. They only reply on the 5th of October, giving me an amount that I'm not sure off. The same-day I requested a summary of the amounts. Today is the 12th, I have requested the summary now 7 times, no luck. I now have cancel the debit order with them (Game RCS) and my bank. I'm fed up with customer care services that doesn't help and then I have to pay interest etc for their mistakes
