I got my money back on all 3 orders the following day thanks to enlisting PayPal's help by phone and on line.
Fast forward and I received 2 of the cheapo flame lickers even after the refund. A couple weeks later they sent a note asking me to pay for what I received because they had proof of delivery.
First of all, I believe the law states that if I am mailed something I didn't order, I am not required to pay for it or return it. I may send them a note advising this but I am not certain I even need to do that.
Under normal circumstances I would reach out to the seller, advise of the error, pay for what they sent me or return it to them at their expense.
Normal circumstances: I describe as.... Seller makes an honest mistake and sends the wrong item and would like to send the right item and fix it. If this were the case I would return the items immediately and the seller would ship what I ordered.
These are clearly not normal circumstances. This outfit can't even package their crap substitutes properly. There were no instructions in either package. No alcohol lamp burner in one package and 3 of them in the other package. Jim received an identical engine with a half dozen Allen wrenches and no burner.
