There are dozens of similar posts on here about delayed installations where VM simply keep moving the installation date into the future. Don't hold out too much hope that the latest date won't be moved again.
Some installations run into problems with installing the cable (such as a blocked duct under ground). When this happens, VM and their sub-contractors seem to have no ability whatsoever to get a grip of the situation and coordinate a plan to complete the work.
The longest (reported here) has been a delay where VM strung out a new connection for 11 months. There's many reports of 3-4 month delays, and always the same total absence of any effective communication, and the appearance of deep rooted incompetence in VM's pre-install and cable re-pull processes. Complaints and escalations (even to the CEO) have proved fruitless, showing that the directors don't care.
Delays and uncertainty are something that is a major risk for any company given the pandemic, along with skills shortages. However, to respond so consistently badly, and to have no working project management, organisation or communications after more than a year can only be explained if the people responsible within VM are intending the outcomes to be this poor.
