I'll take my chances, especially as I've never filled in a form, accepted an offer, or wasted any time on that overrated, over-hyped, useless pretension of a 'raffle'!
What I tried, and seems to work is to answer the phone and then start hitting 999999999999as many times as your phone will take it. Then hang up. If this is an automatic, computer generated call it is supposed to knock your phone number out of their system. I tried it with a couple of phone numbers and they haven't called back, so maybe it does work!
They have called me too. I have an option on my cell to reject the calls I don't want. They can still call but it doesn't ring it gives them a message that I'm not accepting calls. Then it shows up as rejected on my phone. Never even know they called until I see a missed call.
Canadian Pharmacy - This company has been calling me for 5 years, 7-8 times a day. The FTC, FCC, Congressmen, Senators, Verizon, etc. etc., can't make them stop because they're in India. Verizon is so full of [***]. This company is using Verizon lines and yet Verizon claims that they can't do anything about. Verizon is making a ton of money from this company. If I ever visit India, I will track down this call center and murder everyone of their operators. America is supposed to be the greatest country in the world. We are very far from that. I say SUCK MY [***] to all of the people that have the ability to stop this, but don't.
