Svl auctions makes you buy even if you lose

Beware of this online WhatsApp auction group. If you bud and lose they still try make you buy what you lost on. I bid on an item that sold for 3 times my bid, the winner bought some of the items. There were 10 available. Since there was 3 left they asked if I wanted, but it was more than I was prepared to pay. Because of this they kicked me from the group saying that any bidder is an automatic buyer even if they lose!! I have been attending auctions for more than 30 years and have never before encountered such idiotic behavior.
