Our home remodeling took a bit longer to finish, so I called ahead to check if an extension of our coupons was possible, yes no problem. I called again the day before for the ducts cleaning service and everything looked good, they would honor it, which was of sort a pre-requisite to go ahead with the job.
Guess what it didn't happened, the crew next day refused to honor the arrangement.
I sent them off, period.
Unprofessional and shoddy business practice.
Do not recommend.
