No Internet - activation and install issue

Hi. I'm just so disappointed by virginmedia. I had my installation date rescheduled without letting me know. Ok. Wasted day. Then engineer came in and installed my hub 5x. Tried to activate it, but my account was apparently set up for coaxial cable, so incompatible and not working. He called someone and promised that his manager will activate it next day. Nothing happened. So I called VM customer service and after 6 hours on the phone they (maybe 10 different people) told me engineer must come and change the hub. Ok. Waited another 2 days for engineer. He swapped the hub for exactly same thing, and same result vith activation. He promised it will work in couple of hours and that he sent email to his boss. Nothing happened again. Another day wasted. Next day I tried to contact VM, but nobody answer the phone for 2 hours so I gave up. Today I spoke with one technician online (about 2 hours), he couldn't fix it and told me to call VM customer service and ask for tier 2 technician and he'll fix it. I called them and the third person sounds like he knows more about it. Apparently he tried to do something (with muted microphone). Couldn't fix it. But at least he sounded like he knows what's going on. Then he said he escalate this issue higher and within 24 - 48 hours it should get sorted and I can get Internet connection. I won't be notified at any point. I just have to keep trying. So now I give it two days before I cancel my so far useless contract.
