Hi: I ordered from a popular online site a part from Midwest Appliance Company dba mrchgparts a $72.00 part for my daughters furnace. It arrived in brown box and part was inside a plain brown envelope. My daughter and I opened the envelope while at her kitchen counter and took the small part out. It was laid on top of the brown envelope and a photo taken of it and texted to her father. He was the one to install it. He told her it was not the part needed and he would go get the part himself locally. The part was then put back in the envelope and box, sealed and addresses to be returned to the Seller. I opened a return case on the item. Seller received the part and two weeks went by without a word from them. I messaged then on site purchased and they said they would not give me a refund because I had "Altered" the part. A case was filed and I won a full refund from the Seller as they offered no proof of any alterations . Buy from another seller!
