How to use Aextras?

So I am just 200 acs away from Lightcaster.. Instead of buying another packages I decided to use Aextras. But so far I tried... Its s-u-r-v-e-y all over again.. Need some guide on using it or if can exploit it

That's pretty much how those crappy AEextras surv-- work: start with one surv-- then it takes you to another shitty one. I'd stay away from them. Work on the AEextras that makes you watch video, play out some games (if the requirement for the offer isn't difficult to get), and fill out some information like start free trials on some random site that doesn't require you to use any credit or debit cards.

To my knowledge AExtras doesn't really work anymore. I used to get a ton of AC's from it but now, even after 2 hours of completing offers thoroughly, I don't get a single AC :/.
