RCS makro store card

I have had 2 RCS store card accounts for many years. On the 29th of January I paid my total installment due as stated on my statements (due by the 1st) in store. I however sent through the proof op payment of the Makro card on the 7th of Feb, due to my card being suspended. After numerous telephone calls I was told that it had been handed over to the financial department and still to be allocated to my account. Today on the 12th I received a call stating that my account was still in arrears, to which I explained to the consultant that I had paid my amount as was due by the 1st according to my statement. How can my card still be suspended??? I need to use my card. I then phoned into RCS customer services again and what told that in fact I did pay what I owed, so now I am confused. Pathetic service!
