Paid Up Letter ref CCA184269

I paid the outstanding money on 15 Dec 2017. I requested a paid letter on the day after making the payment I was told i takes 30 working days to furnish me with the letter and update my info on my credit report. I then called their Recovery Line ********** 118 on 2nd and 3rd of January with a simple request of being furnished with the letter and I was promised that the relevant dept will send the letter. On Monday the 8th Jan 2018 are called again and I was referred to their legal Department on Johannesburg number ********** 292, spoke to a certain lady around midday she promised that my query would be resolved in 48hrs, meaning by Wednesday midday I should have the letter. Guess what, its a Friday around 11:32 i have called 17 times already no one is picking up my calls, the promised 48hrs turn around time has lapsed. Please advice what must I do
