My salesperson for my appliance purchase was good ...

My salesperson for my appliance purchase was good and knowledgeable, however, everything after the purchase has been poor. Most of the issues are with their subcontractors.I had to wait much longer than initially told for the appliances to be delivered-[-apparently there was one item back ordered, but I was willing to wait to get what I wanted. The worst part has been dealing with their subcontractor who delivered and installed, Diamond Appliances. Very poor follow up- I keep having to call customer care at Furniture and Appliance Mart who calls Diamond Appliance who calls me and tells me they will follow up with me when the parts come in. Then there is never any follow up and I call Furniture and Appliance mart and it starts again. I really liked my salesperson but everything else has been bad. I've ordered appliances from Home Depot and Best Buy in the past and had a much better experience. Until Furniture and Appliance Mart can tighten up their delivery, install, and how to deal with customer issues experience, I would not buy there again.
