very disappointing in this service

It's been 2 days reporting no internet connection and no one seem to understand why I have lost connection. I received 5 resolved case emails confirming I have been called and a technician come to see me LIES LIES LIES. I cannot remember when last I experienced such terrible service. I was unable to work today because of this still no call. I've been calling the call Centre and all they can say is has been EXCALATED. Rain don't understand they own product, i asked for cancellation NOTHING STILL
