Received a call from this number and it only rang twice but I won't call it back. I've heard about scams that do this, ring only twice so that people call back out of curiosity and then get charged for making that call.
I have gotten a call from them twice, one just a few moments ago. Since I didn't recognize the number I let it ring - of course they never left a voice mail either time. After reading this I know this is a classic scam - obviously all they want is SOMEONE's credit card number. Glad you had nothing to give them.
If it gets to the point of being harassment, people-- please contact your cellphone carriers if that's how they're calling you. They can block certain numbers from calling you ever again. I've done it before and it does help, until the next scam artist comes along.
I have a theory about this. They cannot cll you if you are on the do not call list, but if they hang up and you call them back, they can call you back to sell you something because you had called them
Wow, I can't believe you went as far as you did with the phone call. It's clear by your post they are a complete scam. They obviously are interested in your credit card so they can steal the numbers. No legitimate business would operate in the manner you described.
