I've had word back from peanut labs and its disappointing. I post it below for your edification:
Whenever you notify us about an issue with a survey or offer, we make
every effort to mediate with the offer provider or research client on
your behalf. Sometimes they are unable to verify your eligibility for
the reward, which is why you are not receiving credit to your account.
In some instances we are able to make exceptions, but we cannot always
reach this resolution for every request submitted. We work hard at
identifying broken offers and surveys, so we appreciate your write in
and bringing them to the attention of our partners.
This survey was worth 300 credits, too. I have played 266 consecutive days - I obviously need to get a life! - but this issue means that I will now stop playing.
Thanks for the memories, WGT.
