Paying full price for less services

Home Connect Fibre I have been a client for a full year now. I am supposed to get 150mb but only receive100mb. I pay full price for what I am supposed to get. I have been logging fault after fault but to now avail. Finally I found a technician at Home connect Hloni who is capable and his service is exellent. He has done everything he could to sort out the problem as far is he is capable of, I cant say the same for the rest. In Vryheid KZN Home Connect make use of Evotel technicians to install and fix technical problems. Now everything is at a stop because Evotel Vryheid is incapable of sorting out these kind of problems. Neither the supervisors or technicians deliver service, they just know how to request speed tests from their offices. Home connect is supposed to do something about this, should I go through another year of only receiving two thirds of the service I pay for from Home Connect? M.J Nel (Ticket ***)
