Review Poor Service

IAM in Cambridge down at my Mum & Dad place to a 2 week holiday. Both are in the there mid 70s years old & send a lot of time in the evening watching the TV. And most of the time the service is down. Also I found out the this company had cut the service to them saying that the bill has not be paid. Do I pop down to the shop to gone out that it had been pay off. The an account error had been done by them. As far as I can see this company are now worth keep !!??
