Cannot reach Avast support anymore

I just managed to get into chat support. Reached a person and just before the end of the chat and before my issue was resolved I clicked something link which I should not have clicked and the chat was gone.

Now I have been trying to get back to the support page and / or chat page but it just won’t work.
https://support.avast.com/contact/sales_refund
This link gets mit not where it is supposed to.
The page there is empty with the exception of a search field which seems to do nothing.

has the same issue
Basically my paths to reach support seem to be broken.
Any ideas what I could do?
(Already tried restarting browser, restarting pc)

Edit: The working way to get into the chat support is through the unsubscribe link in a subscription. This was the inital way I got into the chat and this way still seems to work. But other ways seem to be blocked for some reason. Using PC, firefox and Avast premium and vpn

Today both links work. What is the difference?
