Getting unwanted calls from this number 305-760-6730 at my work, repeatedly.

They keep talking nonsense like
Prince of Dubai wants to offer me Citibank shares
Arcelor Mittal wants to give me shares
Nextel wants to give me shares

call and make fun of people

Called me three times on my cell phone!!!  Started of by lying that "Patrick" had spoken to me a few months ago and he was following up that call.  Eventually identified his company as JHS, a wealth management company.  I informed him that I am on the DO NOT CALL registry and that it was illegal for him to be calling me for a telemarketing purpose.
