Worth checking on the cover plate in the pavement (probably marked with VM logo or CATV) and whether you already have one or not. If you do have one, that should hopefully improve your chances of an easy connection. If you don't have one that might well hinder your chances.
Usual procedure is typically that VM install in two stages. Stage 1 sees the cable pulled from the street cabinet to your home. The cable emerges from the access plate in the pavement and runs onto your property. The cable might be buried (typically an inch or two below the surface) or might be clipped to a fence/wall etc. or may be laid on the surface in green plastic conduit. A connection box is fitted to the wall outside where the cable from the street terminates.
In stage 2, another cable is run from the box outside into the home and an internal connection point (or points) fitted to serve the equipment and services you are taking.
The installation of cable from the street to home is often done by VM's sub-contractors. If the job is a simple one (i.e. just pulling the cable through an existing duct, emerging from an existing access point in the pavement and easily crossing the property to the front wall of the house, then all should be well. The installations which seem to go wrong on here are where there is an issue with any one of those parts of running in the cable from the street. If this happens, the process can disintegrate into pantomime comedy where neither VM nor the sub-contractor take any measures to deal with the problems. Long delays and failed communications the follow. An increasing number of 'gone-wrong' installation topics on here seem to suggest that this is all down to cost involved for anything beyond a simple installation.
Whether or not any of the above applies to your situation remains to be seen until you have a spotter to tell you what will be involved for your home.
The VM forum team will reply here usually within a day or two and should be able to advise on what to do.
If there is any further mucking about or delay from VM, it sounds like you have already decided on your next move!
