Nimble constantly harrases me and does not issue my paid up letter

I am at my wits end.

I had an FNB account which was being collected by Nimble.

I requested a settlement quotation and was given on on the 23/08/2018 at about 17:00 with the reference FNC123573. I paid the settlement later the same day at 19:00 and sent proof of payment to, ********** as well as ********** upon which I requested a paid up letter.

I still have not yet received the paid up letter.

Yet I am still getting calls on a daily basis from the same call center, multiple times for the same account. I have to tell each and every consultant the same story and then it somehow falls onto deaf ears??? Apparently no one can give me an answer???

I was then told to send the proof of payment to ********** for him or her to sort it out, which I did on the 10/09/2018 and he or she has never even read or bothered to respond to that email??

Another issue is that, the very next day, my account made an automatic transfer for the normal monthly payment, which then meant that I overpaid by this monthly payment as I already settled the account balance.

I enquired about the excess monthly payment being allocated to another account if possible or if the payment will be paid back to me and I have never received any feedback in regards to this matter as well??

Can someone, competent enough to follow up on a email, see the proof of payment attached thereto, allocate the funds to my account (which would have already cleared into your own account) and issue me with a paid up letter PLEASE!

what more must I do? I have held up my end of the agreement but clearly you are not worried nor concerned about upholding yours.

This is not professional nor ethical.

Please fix, YOUR mess.
