Telkom is *****!!!

Since January 2020 when Telkom changed my contract from ADSL to LTE due lack of delivery on their side, they started to bill me for the new contract but every time I made a payment it would go to the previous contract which was cancelled, not only that but the package which we had agreed on was not the one I was getting. I called Telkom so many times to resolve this matter but nothing was done, I went to their stores but the stores kept on telling me to contact the call center, when I called the call center they told me to go the shop. I tried getting the address for the head office but it appears there is no specific head office that deals with contracts. Now its more than a year since I have been trying to resolve this matter and nothing is getting done and now they are appearing on my credit profile which is affecting my life as I can not buy a house or a car due to this. I have escalated the matter with consumer right but all I have been getting is updates for the past 3 months that they dealing with the matter but its not sorted as yet. I don not know where to go to get this matter sorted and getting married as well is a problem as this will affect my partners credit profile.

Telkom Is ***** and the worst company as I don not understand why the law allows them to get away with so much ********ity.
