MBD ****mers and worst service

I made an arrangement with Mpho from MBD last year regarding capitec account, finished paying for it in December but still getting unpaid calls, when I contacted her regarding this she said I must send proof of payment, I did and her response was she is no longer in that department , I sent emails to mbd regarding this, no response whatsoever instead I'm getting calls from agents and been advising them to get managers to call me back ,no response,they never updated the records leftme hanging
