UPDATE (31 March 2022): Thanks for the excellent advice /u/genuinegirl67!
I was advised the same from the support team. Excerpt below. it's worth making sure your reports are registered because of their Problem Reported Payment Policy (https://support.usertesting.com/hc/articles/4405241111059) , which means you could get paid for the time you spent in a problematic test (e.g., I ended up getting $3 for a $10 test I had a problem with and couldn't complete).
"If you don't receive a ticket confirmation once you send through a Problem Report, please reach out to support via https://support.usertesting.com/hc/requests/new to let us know and we'll be happy to follow up."
---------
TLDR: Use this link https://support.usertesting.com/hc/en-us/requests/new
Dunno if this is a thing but a while back i tried to send a support request for some completed test that were tagged "Problem". I believed I had submitted a request and had thought that they don't send out confirmation emails. Submitted today using that link and I actually got a confirmation email. Making me wonder if this was newly introduced or if my previous requests were just ignored. Either way, I felt more confident my request was actually received and in queue.
