Hello, I bought time cards before almost 4 months ago, and I'm trying to add it since 119 days left on my account. but it's not working its giving me error code i2051.

I talked to the support more than 10 times, and no one helped me all of them are saying wait 48 while we are working on it then try and nothing happened it's issue since 4 MONTHS.

and now I've 2 days left on my account, I've raids to do players I promised to play with them, I've house it's gonna be demolished, I've Free Company to take care of.

so please just let me know if now one can help me so I just quit,I get tired of waiting someone helping me (4 MONTHS same issue )

Are you using the correct region time card for your account, they must match, for example you cannot use an EU card on a USA/JP region account, check the cards region and your service account.
Also, there is a limit on how much time can be on your account before it will let you place more.
Did you buy it from the official store?
