Telkom service is terrible. No internet

I had logged a fault that my internet is slow. A technician came to my home and said that Telkom Is no longer fixing ADSL line and he will instal LTE router and cost will be the same. After installing and testing the internet he observed the internet was even slower than ADSL. He then reverted the LTE back to ADSL. The internet worked for a week. I then logged a call to Telkom fault and no one had called or came to my home. I called the service center and they said that my number has been ported to wireless and NO technician will come out. I explained that I have no Wireless internet or equipment at home and request Telkom to correct the problem. Service technician said I need to call accounts to change. I called accounts and said I must call sales. I have been trying to get through sales for the past 3 days and only being meet with a automated answer machine telling me I must go online to register !! I got no internet. I have been waiting on the phone up to 4 hours. Telkom service is pathetic. The technician from Open serv created a problem and I’m left stranded. I don’t have access to LTE or fiber and wire internet is the only thing working.
