Service Blackouts

Recently moved into a new property in April which had Virgin installed in by the previous owner. Decided to continue with the same provider. First few weeks, no issues, steady internet, no blackouts, etc. Then we started getting blackouts of service where it would go off for hours, at various times of night and day. Resetting the hub did not improve this, nor did customer services sending signals to the hub. An engineer was sent around and advised that the connectors were all rusty and was the reason for poor service. He then advised he would book a repull of the cable from the road to the property which should get me the speeds and service that i am paying for. Unbelievably i had to wait three weeks for the repull. It seems that if you are getting some service, regardless of what you are paying for, you are not a priority. I get my text to say that the repull will take place on the 14th August, and that i do not need to be in the property. 14th comes and goes, no show. Call customer services, no explanation as to why they never turned up, and have now had a revised date of the 28th for the repull. This is five weeks after it was first requested. Customer services are shockingly bad, just fob you off to get you off the phone. Promised a credit for the poor service, still not hot snything. Anybody else had the same issue, and if so was it resolved?
