I changed my home number and just started getting calls from this #. Im thinking TELEMARKETING. Anyway, if you are getting the calls on your cell phone and have Verizon...you definitely can block them...just simply call in to CS and give them the # to add to the block list...it will be blocked up to 3 months...you can call back then to extend it. As for the home, I am calling ATT & hopefully they will be able to block the number for me.
