bad customer service

im not happy with their customer care system in place. i missed a payment and after that ive been making payment for every month, one of their collection team members called and advised her that i am going through financial strain but will try to keep up however the outstanding payment i will make end of August 2022 my account will be up-to-date .continuing making monthly payment until then and i dont appreciated that my son be humiliated infront of ppl being asked about the account as he is not responsibly for it. my account has been suspended even when i communicated with them and i send an email this morning with no respons i called on *** spoke to Maphuthi and was denied to speak to their managers or have their contact as theirs nothing he can do i must just pay the account in full or wait for their external collection team to call me... When i took this account it was done for my son health reason and i find them to be cold and have to interest for people.
