Whole bunch of scams!!!! Everybody must beware of this buyer. The buyer takes advantage on the ebay's buyer protection program. They claimed the item is not functional and a return was accepted. However, what buyer returned was not the original item that we ever shipped out. It's not even our property. When we sent them messages about the suspicious they never responded. Then they escalated the case because they know ebay would decide on their favor. This is shameless! All sellers must be careful.
