When confronted the seller contended to me via Facebook messenger that they had immediately overnighted the product via FedEx - on a Sunday. What a Scam!
I am trying to get my money back from PayPal. Tip: file your PayPal resolution request before seller provides you with a fake FedEx tracking number.
Update: It took PayPal about 10 weeks to fully refund me. Turns out: Chestt IS indeed a big scam!
