Nimble Collection services are not only collecting but are ********

I took out a loan with Wonga some time ago and missed my payments. My account was handed over to Nimble and I paid up my entire outstanding amount that was visible on my Wonga dashboard account meaning I owe R0 to Wonga. These people never indicated interests on their dashboard or send me any account statements indicating the interests.

After paying my accounts, I came to know about this company called Nimble who have me listed on Clearscore(Wonga collection services) that I have an account with them with credit of four hundred thousand and when I take it up with them they ask for proof and when I provide proof they want information that’ll break my credit score further as they want my credit report. The other thing is on the phone when they contact me I’m being told a different amount from the amount that is outstanding because what they tell me on the phone is I owe 8 hundred and odds rand, I know it’s not more than R850 but they have a debit order set on my account for R880 due for this month end. How do I know if these *****’s will misuse my banking information. The consultants lie and are really good at shifting the blame to the clients without taking any accountability.
