Utterly utterly disappointed. Fed up. Faulty router. False promises. Empty promises. Bad services

Everybody told me Telkom is the best for wifi. I gave it a try to my utmost disappointment. I have a unlimited 5g home wifi contract with them plus a phone on flexon 2 and a flexon 10 all on one account. I pay more than a R 1200 p/m for my wifi and the two additional sims i can barely use when im at home. Ive went to the store 4 times now. Everytime the issue will get escalated and they will sort it out. But till today nothing. I joined telkom at the end of August. Its now two months that i couldn't use my wifi properly without the router constantly restarting or the network completely disappearing. I was promised the best wifi and speeds now im stuck with a router that i have to pay of when i want to cancel the conrtact even though its not working properly. Im still Also waiting for a technician to call me for over a month now. NOTHING. WHAT IS HAPPENING TO CUSTOMER SERVICE IN THIS COUNTRY. I was also told that ive got the best coverage for 5g i can't even pick 5g up in the area. Im so fed up with this cat and mouse game. I work my ass off for what i want and then these companies just come and make **** empty promises and nothing works just to get ur money month to month and dont worry about the rest.
