Duplicate subscriptions via Adobe Stock voucher

Hi,

after redeeming a Photo subscription voucher I "won" due to image sales on Adobe Stock, instead of prolonging my existing subscription (apparently Photoshop, not Photo), I now have two parallel subscriptions for more or less the same thing. I also cannot quit the yearly Photoshop subscription because it is still running until July and therefore overlapping 7 months with the new one.

Obviously the useful thing would be to have someone from Adobe check and hopefully merge/change the two subscriptions, but it looks like Adobe has made it their primary objective to not be contacted by existing customers.

Any ideas how to fix this or how to contact Adobe via email (or phone in Germany)?

Best regards,

Michael
