I’m getting calls 24 hrs a day 7 days a week and 95% of then are automated. Talking about student loans, extended car warranty and other assorted crap. A bunch of them don’t answer at all to my hello. I want to know about, and if I contact them, will it put a stop to these nucence calls? Please tell me yes!
But, back to today. I knew it was to gd to be true, but I tried it anyway. The site on Facebook said they had an overstock-of IPhones. I had to complete the questionnaire to see if I met the criteria to qualify. I did qualify. Then answer like 50 questions. Then I had to make a purchase. I chose iTunes. Then it would not let me back on site to claim a gift card and the phone. I tried 3 times.
I contacted them and explained everything and they never responded. Only you. But then I was overwhelmed with calls about life insurance n crap.

So please help if you can.

Well I’m a Project Manager and I have to answer my phone and majority of my calls are numbers I don’t know yet. The heck of it is, they use local numbers to trick ya. Not from another state or city.
