As you know, you can sign in to Fever through your Facebook account or Google+ account. When you log in for the first time, your account is automatically linked to the social network you have selected.
In these cases, it is common that your tickets "disappear" mysteriously, because you have bought them with one account and have logged in with the other. You will not be able to redeem vouchers correctly either. For these reasons, if you think you might have more than one account, contact us at firstname.lastname@example.org and we will help you solving this issue.
