SCAM!!! Claimed it was a courtesy call for going over data usage. I have an unlimited data plan. Which I did not mention. Asked what company he was with repeatedly, he avoided it. Said I had had unusual activity the past week. I knew that was a lie. I had just checked my charges and plan the night before, which I did mention. He ignored my comment. He asked to charge my card "on file". I have no card on file. I hung up immediately.
