I've been talking to Spotify tech support through live chat for 2 weeks now with no resolution they just keep saying "Upon checking backstage we have already coordinated this with Google and we are now just waiting for an update from them. Thanks for bearing with us on this! Although we are unable to provide an exact time frame rest assured we are working this to be fixed the soonest."
I have tried the promo code value also listed in the URL which produces "Code already redeemed" Spotify needs to fix and resolve this ASAP!!!
