I purchased the required amount on GoDaddy via the WGT link, but did not receive my Credits.
You need to contact TrialPay via their support link on the offers page.
Thanks. I didn't see any Support link before.
That makes three of us who have bought the godaddy package and not been given the reward credits - I can see my transaction on the "get support" page - but going to support is totally useless as it says you have to go to Godaddy for support. BEWARE THE CON
You cannot get help from Go Daddy. If you go to the page where you chose the offer, you will see a support link. This will put you in touch with Trialpay who will issue your credits right away if you have filled all the requirements.
