Appalling service from Telkom

At the end of Jan 24 I took up an LTE Sim only contract with Telkom on which the first debit order/ payment was to go off on the 25th of Feb 24. On the 25th of Feb the funds went into the account late, and I presume after the debit order has run that is when I tried to contact Telkom to advise them that there were funds in the account and request them to re-run the debit. This was in vain however on the 1st of March the debit order went through successfully and as a result I did not worry further. With that being said on the 15th of March, the debit order of R1 207.54 was ran again. I am not even sure what the debit order was for as I did not owe anything at that particular time, and I have no idea how I could have accumulated a bill of R1 755.54 (i.e. R548.00 + R1 207.54) in one month. I then made numerous calls to Telkom trying to find responses to this and to date I'm still making calls where no answer has been received. I've spoken to call centre agents and their team leaders who have committed to look into the matter and send me emails confirming the reason why the second debit was ran in the middle of the month, however I am yet to receive anything. To make it worse, the invoice is reflecting a name that is not mine. I queried this and was advised that I will have to go through to their branch to have the name rectified. I then advised them that I was not prepared to go to the branch as I did not have the time, and that the error was on the side of Telkom. I must mention that all the agents I spoke to, had a very bad attitude and were not even willing to assist. They were arrogant and did not care of any implications. Instead of Telkom resolving my issues, I have since learnt that my account was cancelled as I'd indicated that I wanted to log a formal complaint before I close/ cancel the services. Subsequent to my account being cancelled, and the instalments for the 2 months I was with Telkom were debited on the 1st March and 25th March, I was advised that there I had an overdue amount of R1 207.54 as at 02/04/2024. This is after my account was debited for the amounts equaling the R1 207.54. I called billing and they had confirmed that all the payments have been received as per the system however I still have an overdue amount. I've trying to get confirmation of what the overdue amount was for however the agent just advised me to "JUST WAIT", in fact she actually shouted at me. I requested a reference number for the call, and she told me there was no reference number as she had not logged it. I requested it however she just told me that there isn't any.
