This foreign jerk has called my phone about 20 times and WILL NOT STOP!!!! He's told me to suck his.... and other vulgar things. All I asked was to be removed from their call list!!! How to I report them???

I've blocked the number directly through Verizon but OMG!!!

Now he's just calling from multiple random numbers!!!! What the heck am I supposed to do about this??? I don't know the company. He is so crude!!!! I do direct sales and have 1,000's of business cards, I can't afford to change my phone number!!

You mention Verizon, is this a cell phone number you have that the spammer is calling?
If so, do you have a smart phone?
If so, there are many apps for filtering calls.
Also, report all of the calls and number to Verizon.

Otherwise, if you can for a day or so ignore all incoming calls, let them go to voice mail, the spammer will most likely give up as long as his doesn't get a live person on the phone to annoy.
Nut-jobs tend to get bored quickly if they do not get a reaction.

It is a smart phone. I've blocked it on my phone too, but now he's using "unknown" and "restricted". How do I block those?

Some of the apps can be set to block unknown or restricted.
Also, the User Controls on your Verizon Wireless account page can be set to block those types also.
Log into your Verizon Wireless account on the www.verizonwireless.com website.
