I just received a call from the same number from a man with a strange accent, also stating that I had won a lottery for 2.5 million dollars..at which point I said "yeah right" and hung up on him...the phone immediately rang back but I flipped the phone on and off again disconnecting the call...

We recieved a call from the above number telling us we won 2.5 million dollars and a new car.  My husband hung up after the guy stated that the only thing we needed to worry about was the federal tax on the car.  The guy called right back and my husband requested the company name, address, his name etc. explaining the he would return the call after we research the company through our local police department.  At that point the man hung up on my husband.
