Got a call from these bozos at 8:15 AM this morning with a robo call claiming that I was overcharged and that if I visited their website I could fill in some information and see what my refund was.  This has SCAM written all over it.  Deleted the message and block the call.  Any legitimate company that over charged me would simply credit my charge card with the amount and send me a letter or e-mail letting me know that they've refunded the overcharge or it would simply show up on my next statement.
