I have received 12 calls from this number today. When I finally answered, I told them to stop calling, and that I was on to their scam.
The number called back two minutes later, at which point a very nasty Asian (I think) woman told me that she was going to call me back every second of every single day!
They have been calling me every ten minutes. After about an hour I answered it. They asked for a name but I said they had the wrong number. Sounded like a oriental woman
