203 427 0180 is "Reward Redemption". They leave messages about getting $100 rebate/spending cards to big retailers like Walmart. When you actually speak to a rep, it's about value points on American Express (I do not own an AM card)--so they lie about what they are promoting, and robo-call your phone several times a day.
Apparently, you get on this list when you call a hotel/motel 800# when you make a reservation. At the time, they INSISTED on me giving my cell ph# when I made the reservation, and I told them no way. Now they are using my # anyway without my permission, and calling incessantly. ALWAYS make reservations with the local #, not the 800#!
Second, I gave the Rewards rep my "new" (fake) #, then told them I am not nor never will be interested. Hopefully that will work.
