Telkom SA Worst service provider ever!

Phoned Telkom just before the easter weekend after receiving a R16k invoice, they acknowledged it was an error on their side and that it would be corrected before the debit order date. I phoned after Easter to follow up and was told my case was assigned to someone who will get in touch within 72 hours. I kept calling in to check the status and no one could give the name of the agent or put me through to them. I got a different story each time I called and on Friday 17th April my wifi and my phone was blocked so I called to find out why and the answer was because of a billing error on their side the system automatically blocked my account as the amount is abnormal and higher than what I qualify to owe them, still no one was able to help. As it is, a debit order of R16 000 is going to go off my account on 25th and I am not even getting hold of anyone to help me at Telkom. What about the days I went without wifi and phone? What a Joke!
