I,ve had this too on several occasions but to be fair WGT did validate the credits after investigating.
You guys are lucky you can do surveys.
The surveys I get are all in Spanish and while I speak some Spanish it,s not nearly good enough to participate in the surveys.
I took it up with WGT a while back and asked them if I could do them in English but they said it,s not possible. I suppose it,s because I live in Spain and I,m registered from here.
I feel a bit miffed as I,m at a disadvantage as the only way I can get credits free is with the videos and that,s a long slow process.
