I reported this number and was told it is a scam to try and get your info. They use a robocall to capture live numbers and then will call to say they are promoting gift cards or prepaid services and try to get your contact information and identification. Furthermore, my local police fraud unit says these are becoming more common as companies are experiencing breaches of secure information online. The officer told me, never answer a cell phone call you do not expect or recognize. Have it blocked if it repeats.
Received two calls from 201 367 2172 on 6/ 5/2014 at 3:46 and 3:49 pm..one ring and then hung up; called back three minutes later one ring and hung up.
