Appliance All Service

I bought a brand new appliance (after buying a used one that came dirty and we had to return) and then the new appliance (a stove) didn't heat up to the correct temperatures - checked by a temperature gauge - and when I called to have them fix it or replace it, Appliance All Service said they don't do that and I needed to call the Manufacturer. It was a 5 week old purchase. Sad that companies don't take care of their customers anymore and the customer has to fight for proper care. On the upside, Whirlpool has been fantastic. Going forward I will only by from business that, regardless of manufacturer warranty, will take care of their customers.
