My family and I have been calling them and messing with them for a while. I may run my Call Flooder at their number later on.
4092008101
Update:
I ran my call flooder and let it call 100 times. It looks like they all failed.
Called this number, Talked about porn for a bit.
The support scam numbers have no sense of humor. Some unknown number called and said it was some affairs department. I got freaked out. IRS is more fun.
