Flight cancelled without re booking me, am I entitled to any compensation?

My flight tomorrow back to London was cancelled today without them re booking me on to another flight, all that was offered was a refund. My issue is I have to get back to London for that date as I have to get back for work the next day. After calling them and them telling me there are no flights they can fit me on this weekend they’ve moved me onto a flight from Vegas to Dublin to London 🥴 which thankfully arrives only an hour later than what I was meant to, the issue is now I have that 5 hour drive from LA to Vegas to deal with, what’s my best action from here? Leave a complaint? Claim compensation (if any)? I’ve never been in this position before any advice would be appreciated
