I had a Virgin Media engineer attend my property today who installed the virgin fibre. He drilled through the MIDDLE part of my wall where he put through the cable. The hole is way bigger than needs to be, 3 cables of the same size would fit through it and I can also see through the hole. Its blowing cold air and rain getting in, no mastic was used on either end of the wall. How do I go about getting it resolved ? Makes me wanna cancel my contract with them right now !
