Am a longtime zwift subscriber, was also an RGT user. I got the email about RGT shutting down, with a redemption code, when I go to use it, I get the following error.
Unexpected Redemption Error.
As already suggested - contacting my Support colleagues is the right path for questions about your account. Any time your money, or promo codes, or other types of private information are involved, we ask that Zwifters contact us offline, instead of this public forum.
I see that you’ve been talking to my colleague Andi via email. Please continue working with us offline, thank you!
