Telkom it's **** to clients

I have a contract with Telkom since March 2024 but the experience I have it's like it's years with their billing department and whole telkom pathetic people if I may say myself they promise to call you and resolve but never. I have been complaining about them and Now they put my account to debt review for what I don't know. As they take money as they please in my account and in wrong dates as well. And cutting my wifi connection plus while you paying them. And worse want to blacklist your name people of South Africa don't go to a service provider called telkom this other day a client to my work was complaining about Telkom as well I even advise a client go to hellopeter ND name them about their treatment as well since they not doing to rectify a mistake because I'm also a victim of their negligence because are really careless about clients they don't live to their logo shame.
