Express Appliance Repair

I purchased a dishwasher from this company last year, it was used but it was supposedly like new, tested and worked perfectly. I then had them deliver and install it in my condo, the installer said it was missing the correct hose so they had to order it from GE. Almost two months later and 20 calls to the company, the owner (that ignores calls after he makes a sale) and to the installer, my part was received and then installed for 100.00. But not installed properly! He had connected two hoses together which caused major leak in the unit which created mould throughout the year and damaged two other unirs below. Long story short, over 25k damage because they use unlicensed installers and sell garbage used appliances. When I called customer service to ask if there was anything they can do they offered 10 percent discount on another used appliance, then when I asked to talk to owner so they could simply send someone to take a look at it the lady hung up on me. Also note, the dishwasher was barely used as my tenant, one girl used it only a few times and was away a lot. Then when I called back the customer service hung up on me. Rude unprofessional company.
