Very angry and frustrated

I have an contract with Telkom and their service is very bad. I recently relocated to Kinross and have a contract that connects to a router. Ever since the 5th of April 2018 i could not connect to the wifi. I did visit the Telkom branch and they could'nt help me of which they did log a call with their Help line. They promise to call back but nothing. The consultant at the call centre inform me there's nothing that they can do and if i want to cancel the contract i have to pay the cancellation fees of which its not my fault that they don't have a tower that connects to Kinross. I have to drive all the way to Secunda to connect to the WiFi of which it cost me a lot. This is very bad because i have to pay for a contract that i cant use at my convenience. They also charged me last month R849 where as they promise me that i have a limited contract and cant exceed my data but that was not the case. I'm really frustrated because i have to pay the price of Telkom. ref numbers ********** 2, ********** 5
