Payments not being allocated every month!

Without fail, I get called about 5 times a day from your call centre telling me that my account is overdue. I always pay via eft but for some reason your system doesn't pick it up even after emailing proof of payments over and over again. <br> This month I did pay a couple of days late, being over festive season. I got an sms stating that if payment is not received by the 9th my account will be in arrears and listed at the credit bureau. I paid it, sent proof of payment and yet still received 3 calls from *** today. Included in these demands is the amount that is due at the end of this month!<br> <br> I've asked your latest caller to send me a statement of my account so that I can pay it in full and never ever have do deal with you guys again. <br> <br> Thank you<br> Tracey<br>
