Unauthorized debit orders

I have been retrenched, called MFC and sent the e-mails regarding my situation, no help was provided, when they are on the media they claim "to help and listen to their customers" and that's a big fat lie!

On the 7 Jan 2021, I paid in R10 700 into their account, I was then contacted by Phillip Mosito who is a collections agent to tell me that my account was handed over to him and he needs to come take pictures. I told him that the payment was made and proof of payment was sent, he then kept quiet till to date with no feedback what so ever. I want to know, why was my account handed over without any call nor feedback from MFC???

They still debited my account with R4 949.94 even after I paid them the full amount (even extra - R10 700).

MFC even has the audacity to say that the unauthorized debit order was agreed where I did not do such. Nedbank refuses to reverse this transaction as well.

This is my money, My kids needs new school uniforms and you are busy playing who has the bigger ****. Just bring back my money.

Below is the e-mail that I have sent to *** as well as

Please note that this account has been corrected, R10 700 was paid in as per attached and yet MFC still debited me R4 949.96 with the ref number NEDMFC .

I did not agree for them to debit my account with this amount and also, why was this account handed over to you without any sort of assistance nor call from MFC?

I trust that the unauthorised R4 949.96 with the ref number "NEDMFC AGREED" will be reversed back into my account no later that the end of business day today.

Hope that the above is in order and trust that this matter will be resolved soonest.
