****med to get contact numbers

So I received a call from PL a while back and answered all the questions and received my lovely gift (thank you for that, I'm loving it). I then received a call a few weeks after that and was told about a so called draw to win R20000 cash. All I needed to do to enter was provide contacts, and if I provide more than 45 numbers, I will get a gift voucher from Isabella Garcia to the value of R1500 to spend on anything I like. So, as I am enjoying my initial gift from Isabella Garcia, I provided over 46 numbers and I was told within 2 weeks, I will receive my voucher. so now I am sitting with my finger in my ear, no voucher received, and my friends are annoyed with me. I cant help but wonder if this was just a ploy to get numbers? is there even this so called "draw" happening in September like I was informed? I'm really disappointed. *** guys?
