Uninterested and unorganised sales and project team

I app**** for fibre on 4 October 2022 and gave approval to proceed. Three weeks later and after dealing with at least 5 consultants in the sales and projects team, still no response. I’ve called at least twice a day and they always say the project co-ordinator is unavailable and can not explain why they have not actioned the installation and what the current hold up is. Their go to is “we will call you back”, to date not a single team member has called to explain or even responded to my emails where I’ve raised concerns. At this point I’m about to cancel and find another supplier. They are completely uninterested in assisting or communicating and if the sales and projects team is this unorganised, imagine trying to get support when anything goes wrong.
