Loan Settlement amount revised after paynent

I have written on hellopeter with regard to loan of R283k that was handed over to Vertex after Capitec staff failed to offer me a settlement amount informing me to pay off the arears first..The account was handed over to Vertex solutions and i had requested a settlement amount with discount and i was asked how much i was prepared to pay and i then said i would settle for R150k and i then received an email and few calls telling me to revise the amount to R174169.66 and then write a motivation stating where i got the money from, where i work, the industry and why i would like to pay that amount and i wrote 2 motivational letters and i then paid R174 169.66 on 12 March 2022 and now i am being told that the new settlement amount is now R203k and that i need to pay off an additional amount of R29k. I will not pay off any additional amount and for as long as Capitec does not intervene and close this account since their debt collectors are greedy and want to rip me off, i will use this platform until my account is closed and updated as such on credit Bereaurs. I am angry and vertex lady made me angry today by telling me that capitec will take the R174169.66 as normal payment and i will require to make new settlement arrangement if i wont pay R29k now. Capitec must intervene and close this matter as it irritates me and via their staff were also not cooperative when account was still with capitec. My decision is final that the agreed amount paid of R174169.66 will remain the final settlement amount on my loan and i want to see this loan account settled and updated at credit bureaurs. The loan account number *** is now increasing and now balance is R290k and will increase again this month and i will not pay any additional amount due to Vertex agreeing with me on settlement amount that they now increase to R203000. Simply because i immeditely paid off the amount does not justify their greediness and decide to take advantage of me by requesting additional amount of R29k. Capitec, please investigate this matter and request proof of payment on 12 March 2022. i will not pay any additional amount and this matter will be reported on all media platforms if not addressed properly
