In Arizona, got a call from this number, didn't answer. A recorded message saying they had sent me something in the mail about my credit card and doing something to reduce my interest rate, blah blah blah. No doubt a scam. Left no company name or any other information.
If you answer, you're just confirming to them that your number is active and therefore valuable. They can then sell it to others as such. Them saying "can you hear me" is just a ruse. Best thing to do is Don't Answer, whenever its a number you don't recognize.
Monday, April 9th @ 4:35pm -- I just got a call from this number on my cell phone, did not pick up, disconnected the call, don't recognize the caller & don't want them calling me again.
