MBD Bad Service

I had a Foschini account and was handed over to MBD. on Monday I spoke to an agent name Caroline from MBD I requested her to send me the account details in order for me to settle the account. She emailed me the details and the amount outstanding. I immediately eft the the out standing owed amount and emailed her proof of payment. Today I phoned MBD to confirm how long does it take to get paid up letter. No one could assist me I spoke to 6 different agence. I also emailed Caroline no reply. Should I not receive my paid up letter I will report MBD to every news paper and Ombudsmen. I will make this my mission this is not a treat but a warning. I have all the proof that I settled this account
