Hello,
Thank you for contacting the support and we are deeply sorry for the unexpected delays and any inconvenience that might have been caused due to that.
Could you please clear your website cache and let Google crawl your website again?
If that doesn’t fix your issue, do note that if everything’s fine and Google still decides to show a different meta title for your search keyword, there is nothing you can do as Google sometimes ignores the custom meta info altogether and show something from the page’s content that matches the search intent better.
Here are some of the common reasons Google might not use the meta title/description you provided:
– The meta title/description is not relevant or useful (ie, just a collection of keywords).
– The exact same meta title/description is provided across a large number of pages.
– The meta title/description doesn’t match what the user is searching for, but other content on the page does.
There is a whole article dedicated to this on SearchEngineJournal:

Here is an example showing Google changes title depending on the keyword used:

The best you can do is optimize your meta tags to try and match the intent of the search/keyword.
Hope that helps. If you have any further question(s), please let us know.
