P45 and final pay

[Forkthenspoon]

Worked at a huge company for 3-4 months. Initially promised WFH in interview, it never materialised even after asking 3-4 times. So another job offer came - significantly more pay.
My line manager is in another country, no other colleagues in my department.No support,guidance or feedback.
I resigned
I didn't engage with HR re exit interview
How long do I wait for P45 and pay?

Usual payroll say so if you were normally paid on the 25th you should get your final wage etc on the 25th

How long ago did you resign and what was your notice period? Have you worked notice?
