Settlement Letter for Closed Mobile Account- 8 Months Without Help

I have been going back and forth since last October for a settlement letter with Telkom. The service is appalling. I was able to open a mobile account in less than 30 minutes at the South Gate mall branch. Going forward... I never received any statements on the contract. Fastforward to last year October, I settled and closed the account. I was ready to purchase property and the account was blocking me. This was October 2019. I was out of the country and tried to reach them online byt all means to get a letter of settlement, and did not win. I spent so much money making international calls, while being put on hold forever everytime, and all they would do is say I would get my letter withing 24-48 hours... and at some point I was told to wait 24 days for this very simple letter. I returned back to South Africa in January, and felt maybe I can manage this then now that I am here, and still when I went to the branch, they told me they do not handle accounts and I should call the customer care line. How convenient that I can open the account in store and yet anything related to the account cannot be henadled in store. I have made countless calls to the customer care andd they just take me email address and nothing happens. I have been emailing the billing department and all I get are automated responses with countless reference numbers. I have made noise on the Facebook and Twitter Page. I have inboxed them on Instagram, Facebook, and Twitter, only to be met by the same automated response. I have tried their WhatsApp ine and it does not assit with my query. I have requested for managers and supervisors at atleast 5 different branches and even from the call centre, and no one has helped me. They just sing the same song of emailing me the settlement letter, and no help. And it is even worse because there is no direct line where I can call and have someone handle my matter and someone to hold accountable for this. They will then refere you to the self service portal which is useless, because since the account is closed, there is no active account showing there. And I have never received any statements to atleast show that the balance is zero. On my Clear Score App, this account is reflecting as active and with a balalance of R3727 which I do not understand how because I settled everything. When you call them they say the account shows as not owing anything, but they cannot send me a confirmation letter regarding this. You try to chat online with their agents and you are lucky if you a response. I am now unable to purchase a home for my family, due to this account. I have been going back and forth for well over 8 months, for something as simple as a settlement letter stating the account is closed and the balance is zero. Telkom has failed me and continues to fail me. It is sad and this is digging me deep into depression because I need to purchase a home and something this trivial is in the way and this company and brand does not care at all.
