Is there a limit on how many premium days you can have on an account?
I will edit this when I have a more official response, but I remember reading somewhere there was a limit. But I wasn't sure if it's still true (I will try to find this post as it was from years ago). I submitted a ticket to Payment Support to see if they can provide me with an official response because this is what was told to me on the Payment Support forum-
"I believe it was either 1000 days or 5 years, although this was a long time ago and I'm not sure if this limit is still valid. Unfortunately, I have no means to find out for you today. So you can either try it out yourself and see if you reach one of these limits
or you can simply send an email to [email protected] and we'll find out for you." Regards, Manina (Customer Support) - Payment Support (Forums: Tibia)
