Called me on May 26 and June 2.  I told them not to call that the number was listed on the do-not-call registry.  Person calling claims he is not selling anything, wants to do a solar evaluation.  I told him not to call back or I would report to the FTC.  He then got indignant and asked if I was threatening him.  I hung up and he called back twice.  I blocked the number on my iPhone.  I haven't counted, but think I have about 50 numbers blocked.

Keep getting call from 661-712- with multiple different numbers as the last numbers abd 661-711- and when you return the call it says ...welcome to verizon this number is no longer in service....
