You need to find out what manager is in charge of purchasing and installation. They use subcontractors for the installation. My son ordered Windows last month it's going to be 6 months before they're even going to be in
Doesn't seem there's any email for the store. I'd suggest calling in and if you can't get it resolved over phone, see if you can get the manager's email that way.
