WHAT HAPPENED TO MY PAYMENT

I am a customer with RCS for long time and do sometime EFT payments from either of my personal accounts.In January 2015 I did a payment and by accident put wrong account number, when i was contacted I send them proof that i did paid but later find out that i have put the wrong account number, I informed them and was told they will resolve the matter.Well after 5 months I found that the matter was not resolved and the payment still not reflecting,this is after I have send the documentation 15 times to them.In the meantime I found other payments also that was done to same account number and cannot find that it reflects on my statement.i HAVE CONFIRMED WITH MY PERSONAL BANK AND WERE TOLD THIS PAYMENTS WAS RECEIVED BY RCS. HOW MANY TIMES DO WE HAVE TO CALL, EMAIL,FAX PROOF OF PAYMENT AND STILL NOTHING GET DONE BY THEM.<br> IT IS CLEAR THEY HAVE NO IDEA HOW TO RESOLVE CUSTOMER QUERIES. THANKS FOR NOTHING AND I NEED TO BE REFUNDED.
