iSwitch, I should not have switched !

Having been suckered into switching service providers , and being promised a 10 Meg line, the service hasn’t been able to get above 0.8 Mbs for the last five days. Calling the service line only gets the response that they are aware of the problem and are working on it, FOR FIVE DAYS !!!!. Why promise a service when they are clearly unable to deliver. I wonder what they will say when we tell them we can only pay a tenth of the subscription ?. Pathetic service.
