I’ve reported this to support, get similar responses each time.
Whenever I try to add my visa card I get an error message, or it won’t let me type it at all. I even contacted my bank and they say there is no error on their end, they aren’t blocking Blizzard charges.
After back and forth with support for 2 days, with the same generic responses and troubleshooting guides I finally try PayPal…
It goes through saying…
"Subscribed: World of Warcraft® Subscription - 6-Month Offer
Next Payment: now"
But my account is still inactive… I get no confirmation of my purchase on PayPal, my bank or from Blizzard.
