Telkom taking consumers for a ride

I signed up with a Telkom agent over the phone for a suitable data package for home . The agent did the normal checks and then advised me to take the uncapped 10mbps wifi package. Received it some time back in September/ October 2019 . I have never picked up signal close to what was agreed on . I have been chatting to consultants back and forth since then . Finally after been given the run around a technician came over to my property (5th Feb 2020) . He concluded that the signal in our area is weak . Now I want to know why Telkom is so quick to take payment but so slow to provide assistance/ service? Telkom is taking consumers for a ride. We need to stand up for whats right in this country. I want a complete and full refund from Telkom since they have breached the contract .
