Bought a house & can't get connected due to planning?

Purchased a house, organised Virgin Media broadband to be connected on the 30th October, it's now the 8th September and no one's come out to take a look to see what's required and I wasn't told there was a delay to the connection from the 30th, it's only because i've been obsessively calling. Today I was told that the enabling work was completed on Friday (???? i've not seen any construction work or enabling works?????) and we're due to be connected on the 11th. 

I've been through multiple different calls, emails, online chat sessions, and no one can tell me how long it would take for me to get connected. One chap told me the 11th, but then a few seconds later saying 6-8 weeks. I just want clarity on how long this will take and why wasn't this raised when I first enquired?
