For those who care for someone with Parkinson's disease
It is known in legal circles as the 473/767 Scam|
The 473 number out of Grenada and the 767 number out of Dominica, both in the Caribbean, calls your phone, but it only rings once.
The scammers hope when you see the missed call that you call the number back and that's when you get hit with the charges. While the phone numbers appear to be in the United States, the number dialed is actually an international number with a share of the revenue going to the operator of the number. Consumers are tricked into dialing these international phone numbers, which results in substantial long-distance charges. Because the same laws do not apply to international calls, it makes these areas ideal for scammers who wish to target U.S. citizens.
Advice: "Don't call back a number you do not know if they don't leave a message that makes sense to you. If a caller uses the 473, 767, or any other area code you do not recognize, do not call it back. Instead contact the operator to verify where the caller's area code originates from."
