Becarefull fals adverti*****t. U won a ipad

It seems like in this stone age, u have to be exstra carefull. Receive a message that i won a ipad congratulations, but have to pay for delivery that would take 3 to 5 days, no worrys, just to find out that im actually describing to IScosmetics and before i can finalize payment exsept the fact that they allready took the R34 for delivery i had to make anither payment of R94 off something i dont whant or need. It just shows u how greedy people are getting. When i cancelle the second payment its just notifications of the ipad to finalize payment. To me its fals adverti*****t. Why they just didnt ask me if im going to be intrestated. And it seems like it with all off this kamma this that u won but the **** nose u didnt even registar. I just wonder if there's a way to stop that bull**** sms or mails.
