Bath Fitter Franchising

We had bath fitter out of lombard, il install an insert, surround, new fixtures, plumbing, and they were supposed to install a door but apparently they measured wrong and brought the wrong size and we now have to wait until the end of the month for that. There are some cosmetic issues we're not thrilled with (including a new crack to our tile floor caused by the installer), but the infuriating issue is with the plumbing and with the utter lack of customer service availability on the weekends. This work was done on thursday, april 11. We were told not to use the tub/shower for at least 24 hours so the caulk could dry and we didn't until saturday, when we discovered that we have almost zero water pressure if we turn the water on hot, and what does come out is tepid at best. Then tonight, as my husband was taking a quick, not very pleasant shower in the trickle of vaguely warm water, the drain slowed almost to a complete stop. It took a number of minutes for an inch or two of water to drain. I have left yet another message for them, and he will be speaking with them tomorrow to arrange for these issues to be fixed (i'm honestly not too hopeful based on what i'm reading here), but the real problem for me is that the issues shouldn't have occurred in the first place! Also, the ceiling panel wasn't installed as the measurements weren't right, and the salesperson just flat out lied to us, telling us the warranty was transferrable should we sell our home in the future, which, upon looking at the warranty we were given after the installation, we discovered is not the case. Needless to say, we are both livid, and we want them to come out here and fix everything they did wrong as quickly as possible. Their customer service person told my husband the doors would "probably be in in under two weeks" but that they won't be installed until april 30 because "we don't have an installer available until then." so they measured wrong, ordered the wrong doors, and then put finishing our project on the back burner? Totally unacceptable. I was not home when the plumber was here but my husband said he smelled and acted as if he'd been out drinking all night and come to our home directly after. Everything about this situation is an absolute affront to us as consumers. We used this company so we didn't have to go through the cost, time, and mess of using a contractor, but we now wish we'd just done that instead.
