I called the number back, it's the Police Officers Association of Michigan - the recording gave an alternate number of 800-365-1632 and hours of 9-9 Eastern. They are seeking donations, and may offer something in return. Last year, one of the nearby cities police chief - speaking to a group of citizen academy students - explained that the Police Department does not contact residents for donations. These companies keep a sizable portion of the money collected and very little (if any) goes to the Police Department.
313-334-3474 has called almost every day for more than a month. If we answer, no one is there--just an odd sound like someone driving with the windows open. If we don't answer, our message machine records the same noise. Says "local area call" but we aren't 313.
Ive received this call and I dont answer it, Id advise you not to. Being a Police Officer I know this is a bogus number possibly from the prison so that they can use your number to pay for there collect calls.
"Do not answer this number". if you do check your phone bill later and if you have a collect call on it notify your carrier.
