Route connection problem

Iv been having a challenge with my route through. However only ti find out telkom has a very bad connection in mamelodi. In most cases i struggle for the route to connect and when i get to telkom to check what could be the issue nobody seems to know anything. Yesterday the 24th i went to telkom seeking cancelation of the route however they said i need ti pay 1400 for the cancelation however even the consultant at menlyn couldn't answer me when i asked why do i have to struggle every month which i end up purchasing data..... Why cant they say that in certain areas it doesn't connect. I really need a cancelation ASAP. I wanted to port my number but i haven't meaning ill be missing on important things.. TELKOM I DON'T WANT TGE ROUTE ANYMORE. THE NETWORK ITS BAD. Nd no one can answer for that instead they wil say alit if clients from mamelodi complain. What is done about that??? This its a waste of money and petrol having to go ti telkom every month...
