I was subscribed to the "Photography plan (20GB)" with 34 months left (not a typo). Last night I tried to increase cloud storage, so I went to "Manage plan" and selected "Creative Cloud Photography plan with 1TB". This inadvertedly cancelled my "Photography plan (20GB)" and the 34 months that I had left. I tried to revert back to "Photography plan (20GB)" and it created a new order, instead of restarting the old plan.
I contacted Customer Support 3 times now (once via chat and 2 times via 1-800-585-0774) and Customer Support insisted that once a plan/order is cancelled, there isn't any way to reactivate it. I asked for exemption since I had 34 months left on the plan, and was told no. I asked to speak with a manager, and was hung up on.
What can I do at this point? Searching through this forum, I have seen a few examples of people getting it done (here and here) so I know it's possible. How can I get in touch with someone who can help?
I finally was able to get someone to reissue redemption codes for me. I had to provide them with a record of the redemption codes that I applied in the past. Since they have no way of retracing those redemption codes in their system, they just guesstimated how many months were left and reissued new codes based on their calculation.
In the end, I still lost about ~6 months, but I'm too tired to continue following up, so I will just let it go.
