Odd Installation!

I live in a road that recently had VM fibre installed. 

The process installed access fibre for all houses in the street apart from 6 in the middle (one of which is mine!)

Can anybody enlighten me as to why this would have happened?

Or how I could get in touch with the right department within VM that could tell me why?

There is nothing out of the ordinary about these properties. They are not different to the rest of the street
