Bad Service

Since 2011 I had very bad service which I'm paying for. I moved into a new home had a move address done which took them near a near to sort out. Now i having problems once again with the speed. I pay R998 per month for a 200 download and 200 upload which I'm not even getting 60 download and 50 upload this problem has always been there I call and called Home connect say it Vumatel which is not the case. I had Vumatel at the new premises on Sunday they tested the box on the wall which is Vumatel they get 200 and 200 when we connect the router we don't even get 50 both sides. I have logged calls after called for Management to call me as they now tell me the router can not be replace as its out of warrant. My son is home schooling due to illness this is causing problems with exams etc. Home connect still billing me the same amount but for a lesser package. It not 19 September at 12:00 no reply from any management I keep getting told they are on another call. We have done Home Connect and Vumatel tests it show Home Connect router is faulty.
