Cali, you're absolutely right on the provider not being legit. "She" messaged me out of the blue somehow and said she was available and then when I responded with "who is this?" She said, "Tina", then I said you must have the wrong number as I've never seen that number before.
Her reply was a dead giveaway, "Oh, I thought you paid for ***, my bad".
I dunno where this person got my number, but that is sketch as crazy.
