New address not on Virgin Postcode Checker

Hello All

I am about to move address and have been with Virgin for years. The new address does not exist on Virgin Medias check my availability function. Normally even if you can't get Virgin media your address still appears on the system which is where I think the issue lies. Had a look around the street and it looks like there are fibre lines laid down. 

There are around 100 addresses on the street in question and for some reason house numbers 1 - 21 (missing 22) 23 randomly 37 appear on the address checker and all have virgin media services available. 37 is less than 6 meters across the road from the address I am moving to. 

The estate is not a new build estate. It's been there for 30 years and I find it difficult to believe that when installing the fibre lines they just stopped halfway up the street. 

I have tried to contact customer service and all they did was try to cancel my account without actually listening to what the issue was and the question I was asking. If there is an admin or advisor or anyone who has had the same problem and had it resolved or at least looked at that can give any info I would greatly appreciate it.
