Got a call at 7:40 p.m . from 516-544-3396 Robo call saying, "Your electric bill is due to go up 12%, if you want to stop this, press 1 now,".......I didn't bother listening to the rest. Hung up and blocked the number. Since my phone company is too cheap to provide me with some decent blocking service, I can block up to six numbers "OH JOY!!!" I went to Amazon.com and got a PRO CALL BLOCKER. Claims to block up to 1,000 numbers, I'm up to 112. Cost $65.00. As long as you have caller i.d. service it will work. It's worth the cash if you can spare it.
