calls everyday a few times a day and hangs up when i answer. then when i call back its some text system called answer for prizes look them up can't find any info on them.

Same happened to me.

Calls everyday and when I answer I get one beep than they hang up, very annoying.

Yupp. They called me saying its some kinda of swepstakes or something then asked me if I have a visa, mastercard etc. or something. I was walking down the street with loud cars going by so I couldn't hear too clearly. Get Mr. Number  app to auto pickup/hangup on their [***] on cell phone.
