Inconvenienced by refusing to assist telephonically

<p>I contacted RCS to change my banking details for my Makro & Game accounts. I was told that I need to send a letter from the bank with my new banking details, when just the previous month my banking details was amended telephonically without requesting proof. I did not keep the letter for the new account and I refuse to be inconvenienced by having to request a bank statement which I will incur costs. No other institution creates unreasonable barriers for such a simple request and Ive had no hassles changing my details with other companies. This is certainly not treating the customer fairly. If these debit orders are not cancelled and unpaid debit orders incur penalty fees in the old account, I will be taking this further.</p> <p> </p>
