I got a call yesterday (1/24/2014) from this phone number 562-941-5858, a female, selling home improvement work, using the (old, worn-out, phony) name of "Home Center". After she asked me what work I was thinking of doing, I told her to shove it.
About blocking telemarketers: I track telemarketing calls, so I can see who is making repeat calls to me. I can only block up to 10 callers thru Verizon, so I use each block where it's most needed. Last week I blocked a very similar number 562-941-5831, also a 'home improvement'-type telemarketer. This call could be the result of blocking them.
My suggestion: Above all, don't be nice. They are low-life, who care not about you. You are just a number.
