I had the exact same offers as you, and I've experienced that when getting these offers, its easiest just to use the mobile offer.
Once you've downloaded the file, send "STOP" to the same number used for the offer. This will cancel your order, so you do not pay anything, but tricking the download ;)
When trying to download this Call of Duty Advanced Warfare Prestige hack, its requiring me to complete a survey/offer.
I've 3 options here. 1 download, which could be a virus(i dont know), 2 A survey which I've tried to complete, but could't finish. and the 3th is a mobile offer which costs me 11$.
Can anyone here help me?
