Product : Elder scrolls Online*Issue: I am trying to use a Vanilla prepaid Master card to purchase Eso Plus Membership and i keep getting an error to contact Mastercard or you the game developers. *This exact card i am trying to use had ***$ prepaid on it and i was able to purchase with this same card Summer set upgrade. ** I find it ridiculous by the way that it took * attempts with the same card and the same error and then randomly the Summer set purchase went through.. But now i am unable to use the remaining amount to purchase anything else on your Elder Scrolls webpage. I have had this issue in the past with"" other " prepaid credit cards funny that on a certain day it would not work then i gave up and a few weeks later with that " other " prepaid card it randomly worked. I really wish you guys could sort this out because i have confirmed the funds and even with taxes that everything should go through and even talk to master card twice over this wasting plenty of time on my behalf for no reason at all. Please help fix this issue with the prepaid credit card issues. I also registered the prepaid card to my postal code that is also on my account billing information nothing i do seems to make this easier.
