Worst experience with Wirulink

Had Wirulink install install wireless internet at my home. When the technician installed it's speeds was about 5mb/s wich is what I pay for. After about 2 hours speeds went down to 3mb/s when nothing was running. Next day, speeds were below 2mb/s. I disabled the routers wireless, connected only my pc and checked that no downloads were running. Reset the router and disconnected the satelite. Still the same. Talked to somebody there and told him my story. He claims 5mb/s were being utilised. Asked him for a solution and he said it might be the router, because it is not one of their routers. Now another R1000 for a stupid router. Fine I'll pay it. They sent out a technician with a router. Technician admits that they cannot install a router. After wasting about 3 hours of my time, they claim the router is broken. I am a businessman and my time is valuable. They showed up 2 hours later than what they scheduled. And they also said we need to reschedule and I'm still waiting for a call from them. Worst experience I have ever had with a service provider and we have Telkom, that says alot.
