Very disappointing service!

I paid my RCS Makro Credit Card on 7/11 and to date received no confirmation. Instead I received another SMS that my debit is due on 25/11.. Their automatic replies said i will get a response within 48 hours...still waiting. I sent numerous emails to numerous addresses for someone to confirm receipt of my payment, but to date none received. No email, no call. Calling them is a waste of time too. Interesting how quick they are when you need money but paying it is such a hassle.
