NO Service after they made a promise to install

Its been almost 3 months since we got the cell phone and ever since Telkom promised us they would come out and install a stronger signal on the farm. We could even use this cell phone all this months on the farm. I attended twice a Telkom office in Pretoria as well as twice in Witbank (That's 4 times).<br> <br> All they need to do is what they said they will do. Fixing my connection problems.
