Cell bill and incorrect personal information

I have a mobile contract with Telkom since January. I gave them all my details which I later realized my name was misspelled and the address is incorrect. I am from gauteng but my statement address says kwamhlanga.

I do not receive any communication from Telkom regarding their contract with them as to how they are billing me, no monthly invoices or statements I get billed differently everything and some months I don't get billed at all. Till date I know my contract is R469 including insurance but I have never been billed off that amount instead it more this month my bill is R670 while last month I paid 900 putting me on a negative balance.

When I use my mobile app to communicate with them I never get any responses or the server disconnects and the will be no follow up from them. I have been trying to chat to them to get them cancel my contract because this is not working for me and what is worse is my incorrectly captured personal details.

Telkom service is poor all they do is have me talk to a machine with automated replies that never helps
