HD channels rubbish, all blocky, already had engineer out who has fitted a powered booster things, after drilling more hole in the front of my home to run wires, replaced all wires inside my home and signal still crap on both of my v6 boxes, can't get thru to anyone on the phone or chat, any help from people on here
It sounds like you have signal issues, that VM need to further investigate. And without knowing specifics of what kit/cabling has been worked on, and having "hands and eyes" on your kit, it's tricky to comment further.
You probably won't want to hear this, but calling faults, and having another engineer visit (and repeating the process until the issue is resolved) is ultimately the best way of fixing this.
