I've received numerous calls from this number. I've told them to stop calling me, cursed them, hung up on them, screamed at them, called them back and hassled them, requested to speak with a supervisor and be taken off their call list.
I called them back 15 times in a row and didn't say a word to them when they answered. They took my number from caller ID and threatened to turn me in! What ever that means !!
Have some fun with them and keep calling them back. I like to speak with an accent and act really stupid to keep them on the phone.
