I missed the original call, so I called back as I have family in NJ in that area code. A recording picked up stating, "press nine to be placed on a do not call list" and then in about 10 seconds the call terminated. This press whatever to be placed on a do not call list is a scam in itself, as it shows the people that are calling you that they've reached a working number with a person answering instead of say a fax machine. I would suggest you never press the whatever key to be placed on a do not call list, especially when the recording does not give out any information about the company calling you.
SCAM ALERT BEWARE: CRIMINALS - Custom Service Credit Card Scam This appears to be a mass-caller. Received unsolicited call. Criminals looking for gullible victims. Old scam to get personal information and Credit Card info. NOTE: Hang up calls are a result of the operator being on the line with another person. The auto dialer hangs up and dials the next number until a operator is available.
