Delayed Install

We signed up on 29 November and were given an installation date of 13 December and were told the pre install work would definitely be done before then. I have contacted Virgin 9 times to get a date for the pre install and was told every time it will be "tomorrow". So here we are on the eve of the install and it has not been done. I called the pre install team and was told it has now been delayed due to wayleave issues for digging the road. The thing is, there are no wayleave issues as pre pull work to the nearest pole (right outside my house) was done last year by UPP just before they were acquired by Virgin so there is no digging to be done. My current provider's contract runs out next monday and I require a working broadband connection for an alarm system and CCTV I have installed and we are going away next week until January. My daughter used to work for Virgin and warned me about these kind of problems and the lies I would be told but I didn't believe her. I do now. To add insult to injury, in order to get me to sign up I was offered synchronous bandwidth for free instead of £6 a month extra. Of course, looking at the contract I can see this hasn't been done. So, if it isn't installed tomorrow, I'll sign up for another 18 months with my current provider and Virgin can do one. All the properties in the postcode are under the same ownership and Virgin will not be allowed to install in any of them.
