RCS Account

I have a Makro RCS account, for the past 12 months, i never had a problem with a debit order going off on my account after a made a eft payment. All of Sudden February I made a payment eft as always and RCS deducted a second payment via debit order. I called they said they would reverse the payment but never did I left it there. Now end of March I did a settlement payment on the 24th of March just for RCS to do another debit order on the 2nd of April. Now the call Centre recons me that I need to submit a formal request for a refund, with the refund only te be processed in 7-14 working days.

This is totally absurd and totally unacceptable. As my payment was made in time.
