New upgraded contract confusion

I am on the edge with Telkom now. I just want to cancel my contract and get another internet service provider. We are paying a lot of money every month and have slow internet most of the time. One day in November we get a call from telkom saying would we like capped internet, which is faster and we pay less. Ofcourse we said yes, because the rates we are paying at the moment are rediculous. They said if they don't come and install the new router we get a month for free. We waited about a month, no sign of telkom. When we eventually got through to them they never processed the order, so finally they processed the order. Then we once again, don't hear anything from them. Phone telkom, no they cant get hold of us to deliver the new router. We alwayas answer all our phones. EVENTUALLY the packaged came today. Telkom said the person will help us install everything. He dropped it off and left. We are sitting here with a router and sim cards and we don't know what to do with it!!!!<br> I refuse to pay another cent. Either cancel my contract or fix the problem. By the rate this is going on Telkom owes us a couple of months free! We lost a lot of business through this!
