Nimble must be stopped collecting debt

I took out a loan with wonga and shortly got retrenched, I fell behind with my instalments and was handed over for collection to nimble group. I have tried to make payments towards this account by asking for assistance from different people. March 10th 2022 I made payment towards this account and it has still not been allocated. I have sent several emails, WhatsApp, called in but still this account still remains I’m areas. The last person I spoke to was Amanda Hendricks, promised to assist me to get it allocated on condition that I have a settlement agreement with her to pay off the outstanding amount even after I had repeatedly told her that I am still unemployed and depend on people for support. She proceeded to give me her managers emails Nthabiseng S and the customer care email. I sent the proof of payment and asked my mother to pay R1000 towards this account. Amanda called me the day after I had made this payment and said “they” have found my previous payment which was not the case. She thanked me for my payment and proceeded to ask me about my balance payment. She gave me the customer contact numbers as said I should call them. So her promise to me that the money would be credited on my account was a lie just to get me to settle. I found her underhand dealings distasteful and her manager not caring for the people they collect from. Nimble has added this account on my credit profile making it seem as thou now I owe two accounts when I just owe Wonga and they doing a collection for them. This has to be rectified and my credit points adjusted as I have made payments towards this account and the outstanding amount is for all the calls, sms all the unnecessary costs they have added to my account when indeed I have paid. Please remove yourself from my credit profile I owe wonga not nimble group
