Who called from 3147768381

Recently started receiving solicitations on my cell phone.  This one told me that the interest rate on my credit card is too high.

Scam about credit card payments not made, another one!

Got a call from this number and tried to call it back, NOT in Service?  Been getting a lot of calls from numbers such as these and I have no credit cards!  Is there a way to stop these calls?

Nothing, when i try to call the number back it tells me that i have reached a number that has been disconnected or no longer in service. How is that possible if they just called me from that number?

same w/ me...that the number was disconnected when i tried to call back missed call.
