It happened to me too. I lost $500 points value and elite plus status.
It seems best buy reset account and don't like people using rewards so they can save money on customers.

Welcome to the forum, though I wish you had found us under better circumstances. Finding one's account seemingly reset would be pretty peculiar to say the least, and would have me seeking answers as well.
Generally, there are only a couple ways a member ID may change on BestBuy.com. The first is if a member ID is cancelled, a new one will be generated upon logging into BestBuy.com. Secondly, if you have multiple memberships and the linked membership is switched. I would be happy to take a closer look at things with you, so please keep an eye on your inbox in the top right corner of the page for my private message.
