I just made the payment to your through the link and also sent required details to attach the license, but the automated mail i received from payivy is something like this below.

Thanks for Purchasing WHMCS Licenses Sale
Here is what you bought:
email id : xxxxxx@xxxx
license no. xxxsxsxsx

Does it mean that license is not attached to my mail id as you said above, if not then do the needful
