I recently ordered a $20 part and by the time I got it with shipping and there was COD on the shipment which ended up costing me $80!! They said I could send the part back.
Many years ago Kenne Bell sent me the wrong injectors. I sent the old ones back and told him to take care of the paper work for the exchange. He said, "No problem!" I was like, good. Then I get my right injectors and get an invoice for $120. I call Kenne, he makes a phone call, then the invoice is $30. Phone Kenne again and finally an invoice for $0. UPS then drops off my injectors, no charge.
Weeks later I get a collection agent threatening me to pay $120! I explain that I had paid and return the wrong item in exchange for the right one. And mentioned that UPS only dropped the item off when NO money was owing. The dingbat said, "You still have to pay the taxes on it." I told her I did and if I paid again I would be paying twice for only one product!!!
