Customer service

I am quite frustrated and annoyed by the lack of helpfulness from the multichoice consultants, I made a payment into an incorrect account, I have been calling everyday since the 2nd of July to have it rectified, I have sent proof of payments which they keep on saying they are not able to open I must send it in a pdf format but it is a pdf document then I sent the screen shot of the the statement where the payment reflects, which I did and still they not able to assist, they keep you on hold and then hang up and no one is willing to call back to get the matter resolved in the mean time, I have to pay a late fee on the account while we go back and forth and a waste of airtime.
