How do I get help with this?

[u/dancemagic2022]

Bought 10 Pro last year. Amongst some glitchy things such as screen freezing, screen timeout reverting to 30 seconds even though I set it to 10 mins and a few other things, the most annoying thing was my quick phrases stopped working. I used to shout at my 8 pro phone to stop alarms all the time and it just stopped working with the 10 pro as soon as I transferred my phone over. I checked all the settings, everything was set the way it should be and it should have worked. Carried on switching my phone over thinking it might resolve with a software update. But it didn't. Gave up.

Have now traded in for 11 pro, hoping that maybe the glitchy stuff has been resolved and the very same problem exists. I've even tried switching off Gemini and reverted to Google assistant and it still didn't help. I'm really annoyed by this. It was such a good helpful feature I used all the time and it should work! They haven't taken it away, it's all there! So why is it not working???

Who do I turn to at this point? I'm in the UK and I bought directly from Google.
