This number would call 3 times a day for over a week. I called back and pushed the number to be put on the do not call list, but they continued calling relentlessly. I finally answered and asked who it was then I just hungup because she wouldn't really say and I blocked the number. Very annoying!!!
Pushing that number will assure plenty more calls are coming to your number. They'll just pass your number along since you let them know it's active and certainly don't call them back. The best thing to do is to simply ignore the phone all the way around and make them think your number is dead. I even turned my answering machine off. Now, my landline rarely rings when I used to get swamped daily with unknown numbers and junk calls. Blocking does a bit of good, but they can easily max out your limit with spoofed numbers. Not answering is probably the best.
They call over and over, either offering pain relief cream or diabetic supplies! They say my insurance has approved it, so I asked them....How do you know MY insurance approved anything since I am NOT diabetic and you dont even know who my insurance company is?
