Got a call from 678-832-5155 saying my phone bill was not paid in full. Asked me to call 404-484-8620 to pay the outstanding amount ($4.18) immediately else my phone would disconnected.

The people who answer the phone speak like customer service reps, but they are just a bunch of frauds.

Credit card number I used to make payment was immediately compromised. Thankfully Fraud Prevention Services recognized what was happening and canceled my card.

Yes, these are a bunch of frauds- the intention is to make you panic by stating that they will cancel your phone immediately and give your credit card information- report them to FBI and police ASAP.
