I receive so many if these calls it is a joke. If it is a number I don't know I let it go to voicemail and if hey don't leave a message I call back. As soon as one of these fools with a heavy Indian accent answers I either tell them where to put it or I just hang up,
Depending in my mood. I always block the numbers. I receive a call from these fools at this number today I wish someone would stop this crap.
