Mobile quiz scam. I get sms and emails from them. There is no prize, the only ones winning are them. They send me emails spoofing my email address so you cant block them or respond. When you call this number they request your mobile number so I gave them an old pre paid number that I dont use anymore. They put you on hold because they are busy and then insist you leave a message. I dont know if they got back to me because the number I gave is not in use. A friend of mine lost $300 before I told her it was a scam.

They cost me $45 = 9 $5 calls
