The N.C Attorney General's Office says watch out for phone calls from scam artists using TTY. That's a device that allows hearing- or speech- impaired people to make telephone calls by typing their conversations. It's also a way for scam artists to gain your sympathy and trust, officials say. North Carolinians are reporting that scammers call in response to a classified ad to establish that sympathy and trust. Then they send a money order for more than the cost of the item. The scam artists then asks you to wire the extra money back. The money orders may look real but turn out to be fake. The victim could end up owing the amount of the counterfeit money order to the bank. The N.C Attorney General's Office says never cash a check or money order from someone who asks you to wire part of the money back to them.
