Either website interface or account information problem and no solution from support

I have a HAMACHI subscription which has been active for years now, I was billed on February 2023 for it, my client application is working but I cannot make any changes to the networks, subscription or billing information. Upon entering the site it simply says I have NOTHING of the sorts and offers me to subscribe.

I've opened a support call but it is taking long to have answers and they have been saying there is no problem, despite screenshots proving otherwise and now, with problem still pending, the ticket disappeared from the list as if it was solved.

I there a channel that enables me to have this problem ACTUALLY solved?
