To earn credits its best to use the following :
Carousel - videos
Supersonic Ads - videos
Peanut Labs - surveys & offers
In my time here earning credits I have found these 3 to be the most dependable and reliable of all . I have had very few problems with any of these sites . The other credit offers for surveys will burn you faster than an actual fire . WGT does business with the main site which is who supplies the offers . Even the sites cant keep up with every single ad and offer that is being shown .
Unless you complain to them they cant fix the problem or remove the bogus offers . If they cant confirm your rip off they wont make the offer good . But if you are spending money on offers what you can do is stop payment through your card company .
In most cases you have 30 days to contest any charges or purchases made on your credit or debit cards . So if the offer doesnt make good as promised you can stop payment or reverse payments on any offers that dont deliver as promised . So you can always resolve the issues with credit offers you just have to know how
I`ve been doing this now for 6 years now and have had very good results with earning credits . It just takes time and learning which offers payout and which ones are bogus . So dont give up even though it can be frustrating at times . In the end it will be worth the time and effort .
