Opinion Outpost Western Wats Not getting credit for survey 39674015 that I completed , Internet

I have been taking surveys from Opinion Outpost [and other companies] for years. I have always been paid for every survey I have taken through them. I have been paid 3 times for a total of $90.
One thing you can do to ensure that you are credited for each survey you complete is to take a screenshot of the "thank you/completion page" and attach it to the email that invited you to the survey. I usually mail this to myself, so I have the original invite with the screenshot attached. That way if there is a discrepancy, you have proof.
There have been two times where there was a discrepancy. Both times they eventually credited my account the money, even though the company the survey was for did not accept that I completed the survey.
Proof of your work is essential. Always.
Also, to those who complain of getting survey after survey that they don't qualify for. Have you completed all of your "profile surveys"? Do you keep them up to date? These help to ensure that the surveys sent you are ones that you are more likely to qualify for.

Well after finally getting compensated, for a survey that I fully and successfully completed, at the beginning of October I thought all was settled and pass.  Well they have stop sending me surveys since this issue was resolved.  So I guess this is there way of punishing me for reporting them to the BBB and ripoffreport for not paying me for a survey I successfully completed!  The only good thing about this company is that they do pay well, unless you are forced to report them for not paying, but there customer service is completly horrible!

After over approx. 8 emails and filing with the BBB, ripoffreport.com and making a post about this on Survey police forums and taking over 8 weeks to get credit for the $3.50 survey, they have finality paid. Plus they also paid me the additional $3.50 for the trouble and time spent trying to get the money that they owed me. 

Like I said before in my original post, over all they are a pretty good company and I do like doing surveys with them.  just wish that they didn't force me into a corner and have to file like this!
