Telkom Is the Mafia

This is the self proclaimed SA's best network, but my experience is the worst I have had with any service provider. I opened my wifi contract in January 2020. By Feb 2020 my bill was R3000 on a contract I thought was capped. These extra charges were in arrears because I did not have that amount all at once, not without starving my family. But I was paying R500. I couldn't get a hold of Telkom to make payment arrangements for the arrears and they listed these with the credit bureau as my monthly installments. When it was picked up during my bond application I paid to clear them. I have been trying to request a letter confirming that my account is no longer in arrears to use on my bond application, but contacting telkom is harder than contacting an offs**** business. The store where I took up the contract JHB PARK STATION tells me that they are an "express" store and cannot print such a letter, so does the store in JHB Main street, and refer me to call 081 180. The holding times on this line are forever and I have been cut off several times just as the Agent answered or went to 'confirm' some details. The Telkom App just crashes, together with the website. When I see the home page of the App saying Welcome to SA's best network and that I made the right choice I just want to puke because taking up this contract was the worst mistake I have ever made. The arrears I am talking about were the uncapped part of my capped contract in Jan that I was not made aware of, now my opportunity to buy property is blocked by this gangsta of a company. In fact I tried to cancel in February, but was convinced that it would be better for me to stay than pay exorbitant cancellation fees. I have paid my dues why can't I get my clearance letter? Where do I go?
