Google f*cking up my titles (cannibalization)

For one of my Local SEO sites, Google's "helping" by selecting their own title.

It current reads:

"Service in Area - Company Name - Main KW"

For a contact us, and previous work page.

I'm trying to rank "Main KW" for my homepage, so now all three of these pages are competing for the same KW and not ranking.

I've changed the page titles multiple times, even having more than max characters, and Google insists on keeping my main KW in these titles

Did you try reindexing after you changed titles

Yes I can see the titles change in SERPS, but Google still insists on cannibalizing my keyword

How long are you waiting for the changes to propagate?
