Totally ******* service

Have been receiving extremely poor service from the customer representatives. Only one out of the almost 5 different reps was able to help me and improve my connection. After multiple attempts to contact customer support I am still sitting with the same issue. When I first joined the rain network I could have 3 cellphones, 1 tablet, a laptop and a play station all connected to my router and i would receive stable download and upload speeds. Over the last two months now the network has steadily got worse. It is so bad that I can't even have 2 devices connected at the same time. Download speeds are below 1mbps and can not even run a speed test. The last customer service rep is about as useless as a bowling ball in a tennis match. He tells me I'm too far away from the tower. I'm 1.8km from the tower. I have a friend who is more than double that and he is receiving over 10mbps. What is the point of paying for a service if you don't receive proper customer support?
