Bad bad internet service

We have been with this company for i think almost 4 years now. This past 3 weeks we have had no joy with th internet. You pay for a 10meg line and sometimes only get 4 megs, you phone to complain..... They reset whatever then all goes well for about a week then the same drill all over again. This morning i phone again and then this wizzchap tells me the problem now lies with the dish. It might be that it has shifted so a tech needs to come out. My goodness really spoke too two different people over the last two weeks this is a new one. They will phone me or email me a quotation. How would it be fine the previous week just to reset what the hell ever the next week the same and then the third its might have moved. Bull. Always at the expense of the customer. And will the customer ever know.......... Well offcourse not..... Just pay or no service but service or not your debit order will be taken. Thats what monopoly gives you I guess....... And stuff the client
