Hello everybody,
Could you help me please about these sentences?

Hello Lara,
hope you are well.

Before my leaving I tried
- to catch you (in your office, mobile phone) to say good bye/for saying good bye

OR

-to pass in your office and contact you at mobile phone to say good bye/for saying good bye

A lot of warm regards to Helen and Jonh, also from Riccardo.

Request: Can I use TO CATCH instead of TO PASS and TO CONTACT in the formal form?
Is it correct this sentence?

Thanks very much,

Best Regards,

Lara
