Call about unused RCI vacation rewards points. I've asked about a dozen times to be removed from their list and have blocked every number they call from, all to no avail.
Super vague, overly enthusiastic female caller which is obviously spam/scam. "We're calling because you've previously stayed at one of our resorts and you've WON AN EXCLUSIVE AMAZING 3-DAY, 4-NIGHT STAY IN MAAAAAGGGICAL Orlando, FL..." I hung up after that because anytime I get a call that's super vague such as "Stayed at one of our resorts" or "I'm calling from the credit card company", it's an obvious phishing scam.
