Oh no… why you say that?
Have a read through some of the (many) other topics on delayed installations on this forum. Your description has many of the key ingredients for a delayed VM installation (such as a no-show on the day of installation, VM mentioning 'council permission' as a reason for delay, the fact that you mention digging across a road).
You could try this website
and see if it shows any planned VM activity for your street (it is not a terribly reliable site but might show something)
You should probably also contact your local highway authority and see if VM have actually put in any requests to dig (some past topics have reported VM using this as an excuse for delay but, when the prospective customer has checked, no works applications had been submitted by VM).
