Received many calls with no message left by the caller. I have found other information on the Internet which claims it is from "Always Available Locksmith" and a few others that trace it to another business which took over his number or shares his number from a Bronx, NY location. The caller ID shows only the words "New York NY". However it is they never leave a message. When you return the call you get a recorded message which offers the option of leaving a message or contacting their "24 Hour Support Team". They do not reveal their identity. This is about the 25th call this year. Very annoying.
