Paid up account with no response

on the 25/10/2017 I called MDB credit solutions & spoke to Nomvulo requesting a settlement amount for my Identity handed over account. Nomvulo advised me that I get a 20% discount & will have to pay the amount of R4209.00 into the MBD Trust Account, which I did on the 27/10/2017. I called up the call centre the following week to check if the payment had been received, for my paid up letter & for my name to be removed of ITC. I was then told by (Rachael) a consultant who was very rude that I have a balance of R900+- that needs to be settled first. I advised on my previous call but could not get a good response, therefore I hung up. The next day I received a call from a lady from the call centre stating that I have a balance of R900+- on my Identity account which I disputed. I called the call centre again & spoke to a male who advised me that I had a balance of R0.81, I needed to pay this at the store & thereafter my account would be settled. I proceeded to the store (which was very odd as the 1st consultant ,Nomvulo) advised me to pay through the MBD Trust account. I paid the R0.81 & obtained a receipt which I emailed to ********** Thereafter I called MBD about 18 times, I have emailed, but to no avail. Their customer care lines are always busy, when I did get to speak to a consultant finally I was told that they are awaiting the system to update & will email me my paid up letter & have my name removed from ITC, however this is over 3 months & a new year has begun & I have not received any feedback or letter. The services are disgusting, with rude, uneducated staff. They being a debt collection company has a very negative impact on me. I incurred nothing more than call costs, unnecessary running around & rude behaviour.
