I am not happy with Telkom

I took a contract last year in May with telkom. The thing is I have been struggling with streaming ,which im assuming the telkom network is poor at my area. It will always connects without network. I have been to telkom Alberton city to complain about this as I am paying a very month for the service which iam not getting. Iam paying R527 for uncapped contract. The thing is my complaint is falling on deaf ears. The said the router need to be updated. The guy did that fo us but iam still experiencing the same issue not network. What should one do to get assistance at Telkom. I decided to go for another network which iam using and with that network i don't have any issues. Can I get assistance with this issue. Someone from Telkom who can listen to me and come up with solutions
