I got a call from this number. The person offered me a 2-year saving on my current ATT plan of $648.00. However, a one-time activation fee of $99.99 was required; the agent asked for my credit card number. The agent even knew my current ATT monthly billing amount. I declined the offer. Next, I called ATT to make a report; ATT believes that it is probably a fraudulent activity.
