Disgusting service

In february 2019, i called telkom call center to advise them am not working and going to make cash payments, which i was given a 19 number ref number and i have been paying each month but ever since then ive been charged a reversal fee R202 per debit order. Called telkom in march to find out why but was given a respond that they can not cancel the debit order. I asked them where am i supposed to get money in my acc, call was meant to be transfered to a manger but was holding for over 30min. This has been happening since feb 2019 but every eish i make my instalment to them... I then called in on the 19th, which i found out that they will send the matter to they dispute deparment within 72hrs but today i spoke to nomzamo at 10:47am who said that the matter has'nt been allocated...my line has been suspended for something ive been paying for and the last payment i made is on the 27th of this month as per normal.
