Settlement Letter ABSA Personal Loans

I have paid my ABSA loan Account over two months ago, through a 2nd party. I firstly gave their an amount that I could pay, but they were not willing to accept it and I got help. The promise from ABSA and the 2nd party was that I will have my settlement letter (as confirmation that my account is paid up and fully settled) within 30 days. It is now 2 months and 6 days. I still don't have the settlement letter and the 2nd party is every week saying they will follow up on the letter, but they are making NO effort to get the letter from ABSA nor giving me a email address or contact person that I can contact myself via email.
