Global Test Market not paying out

Have had no problems with them before but the last 2 surveys that I have completed they haven't paid out on

I put in a screen shot only to be told it wasn't redirected back to clix sense and I may or may not be paid for them

I'll try a few more times but I don't like wasting my time if GTM can't get their act together then it is time to stop taking their surveys

AS I said I usually get 1 or 2 GTM surveys credited per day so I hope it is just a temporary glitch
