I answered the call. It was a robo call about "my credit card" and about increasing my credit. There was only a press one to speak to an agent if interested. I pressed one to let them know to remove my number. A man with a very thick foreign accent answered. When I told him to remove my number, he hung up on me.
Just got called. I didn't answer, but they left no message. Glad to see all of this activity; really cements the fact that it's most likely something irrelevant.
