Garage Living

I purchased a house and planned a renovation of my garage. I thought I should start by the flooring, so I called Garage Living for a quote. The salesperson checked my garage and told me that I should fix everything first and leave the floor for last.
So, that is what I did: new concrete floor, baseboard, drywall, including a new paint job. I called them back and finally the salesperson agreed that the garage was ready for the flooring. Given that everything was new, I expressed to the salesperson my concern with potential damages to the newly painted walls. I specifically asked if Garage Living used protective tape to protect the walls from spilling of the coating. The answer I received from the salesperson was that they did not put tape, but not to worry – they were very meticulous in their job and everything would be perfect.
Not surprisingly, the crew ended up damaging the paint near the baseboard all over the garage, as seen in the pictures. I contacted the salesperson to complain, and no apology was made, no recognition of what was done wrong: just a simple answer that they would fix it, as if this was the normal procedure in every job.
The problem is: how can I trust the fixer not to further damage my garage, giving that they do not protect properly the nearby area? I ended up calling a contractor to repaint the wall, this time doing it right and using a protective tape.
In the end, I was truly disappointed with Garage Living and its culture of believing that doing it the wrong way and fixing it later is acceptable. In my opinion, service quality means doing it right the first time.
