Telkom Bunch of ****mers

Telkom has the worst service and their consultants are by far the most misinformed and poorly trained people I have ever experienced. I have been a customer for over 5 years and must say their service is becoming more appalling by the day. Don't think you will get assistance from their managers, they are more clueless than the agents. My account was in arrears for the month of June and in July I made payment that was required of R713, which I paid via a link I received. I called in August to find out how much they would debit as their statement said R900 + and spoke to an agent who told me the payment made 26 July reflects on my account and in fact I have a credit amount of +R500 on my account, so telkom actually owes me, so they would not debit for the month of August and in September I would need to call in to ensure the credit I have still sufficient for September as well. To my surprise I get an sms of a failed debit order of over R700 on the 7th of July , I called them and was told no actually you were supposed to pay R50 for August as your account had credit. But the agent could not explain why they did not debit that R50 but tried to debit R700? I asked to speak a manager who called me back to give me a third version, everyone gives you a different story. He was worse as he wanted to speak over me during the conversation and he couldn't answer why they wanted to debit R700 instead of R50 and more so he did not come with a solution. I requested a cancelation was put through to a rentions line that rings unanswered. Horrible service from Telkom.
