Thumbs up to Trialplay.
Within two hours of contacting them with a screen shot of my A/C with the token offerer they sent me an e-mail.

"Dear Steven,

Thank you for submitting the requested information. We have confirmed that you completed an offer, and your 10 Tokens will be delivered by Facebook Inc. in the next few minutes."

They were indeed credited so fair play to them.
Thankyou Trialplay.
