Complaint Review: Backhander sap paulo

I got an email that said I had won a $500 gift card to Walmart. The only thing I had to do was answer 3 questions in a short survey. It then said the card would be shipped to me, I only had to pay .27cents. I saw the transaction the next day. Then a week later I saw 2 more transactions 1 for .26cents and another one for $41.00!! So at this point I knew something was wrong!! This last transaction said something sao pao bra? Plus I never got the Walmart card. I’d be glad to call this company and cancel them for good! But they seem to be very clever they have no phone number that I can find. That is why I’m turning to you!!! Can you please help!!??Thank you very much Marianne Vigstedt
