Steamworks: long waits and dismissive replies instead of help

I am extremely disappointed with Steamworks support. In my experience, their attitude toward users is dismissive and careless. I had to wait almost a week for the first response. What I received was a generic instruction that essentially amounted to “figure it out yourself” and did not solve my problem. I would never have contacted support if I could fix it myself: the field I need to change is locked and cannot be edited. I explained in detail why their suggested solution did not work and attached a screenshot. Then came another prolonged wait without a resolution. When I opened a second ticket asking them to finally help, they closed it unilaterally, citing their “one issue, one ticket” rule and telling me to wait for a response in the original ticket. Meanwhile, the original ticket still remains unanswered. They managed to close the additional request, but have yet to resolve the actual problem. I have already paid the Steam Direct fee, but I cannot complete onboarding or create my app. Everything is blocked by a surname spelling correction that I cannot make myself. I am extremely frustrated by this treatment. After this experience, I would not recommend Steam to anyone. When you actually need help, you are left with long waits, generic replies, and complete uncertainty.
