I ordered a critical part for my furnace and paid for express shipping. 3 days later NO PARTS and it is -30 here. I HAVE NO HEAT AND IT IS -30 OUT. Their response when I contact them? Oh, well we shipped it so we can't help you. I checked with the shipping company and they created a shipping label 3 DAYS AFTER I ordered the part and the tracking number is INVALID. Their response? We'll get back to you.
