Yes, sometimes it happens!
After having mostly bad experiences with CS this year - and I had to contact them far too many times, as I am sure was the case for a lot of hosts - I also had a positive result last week. It was nothing major, but I got my vanished 2019 Superhost bonus back after speaking to a different rep about it (the previous ones wouldn't help me).
I also battled some wrongly issued COVID-19 refunds earlier this year and dealt with numerous reps, all of whom were useless, except for one, who thankfully sorted out a number of payments for me. It really does seem to be wholly dependent on the rep you get on the line/message system rather than Airbnb policy or the problem in hand.
Unfortunately, these competent and effective reps do seem to be in the minority these days, whereas a couple of years ago, I would have said the opposite.
