I have the same problem as the other users on this website. I ordered a replacement Samsung battery and never received it. Could not get a refund; posted a Trustpilot review on the company stating the same, and the owner said that he would only give a refund after I change the rating from a one star to a five star on the review site.
I am blessed to have used Paypal. Submitted a claim via Paypal and then escalated it; Paypal got my money back. I doubt I would have gotten it back if I had not used Paypal.
Do not use this vendor.
