Debt Buster's- So near ,yet so far

Good day

I would like to report Debt Buster's. In the beginning things were going great and every penny made sense,,but of late getting closer to being debt free by making payment for my last installment I am told infact I have to pay an additional R1300+- because some consultant felt like setting an amount that was created by the provider in error. Unfortunately they have you by the delicates n so I made the payment after calling them to find out what was going on or being done after I made the payment as it was quite,I called in again n spoke to a consultant named Nelly,she did not know how to do her job,I had to instruct her to read remarks on her system to find out what was said or done the last time,the girl was still clueless n basically just repeated the story I gave her.

I want to know how soon will I get my paid up letter n was told it would take 2 weeks as they have to request it from all my debtors,I advised it wasn't necessary as I have paid all whom I owe n had already sent them the paid up letters which they have used to remove the debtors from my profile hence I was just left with 1, which is the account I am settling.

Furthermore I requested Nelly to call me back in a day,I called in Tuesday n requested her to call me back on Thursday with feedback I even said to her please don't make me call you first n that she needs to keep her promise of getting back to the client,I'm not sure if Debt Buster's has heard of a term called TCF- aka, treating customers fairly, taking responsibility for her actions , clearly not I presume.

I find the service absolutely ubsurd it's more than a week n still no response from Debt Buster's bit should I be late with a payment then they are ony dial.

Can someone preferably management as the consultants don't have a clue please call me and resolve this issue.
