I wanted to quit my job but I’m not sure how

Problem/Goal: Hello, I wanted to quit my job. Not because may pangit akong team or nadadamihan nako ng tasks. Kundi sa grabeng pay delays. Di ko alam pano mag resign, kasi first job ko nong 22 nag AWOL ako when my dad died. Like do I talk to my client muna (im client facing) or sa management ng company? What should I say?

My team and I have been receiving emails from HR since last year to expect pay delays, for 5 BUSINESS DAYS. Kasi daw wala pang binigay si client for salary (??)

Lalo na ngayong holiday so sa April 10 daw pa marereceive yung 3/31 (YES 15/30 kami pero sabi nila evey last day of the month daw dapat rerelease + 5 biz days delay)

Anyways, checked my pag ibig contris at andaming months di nabayaran. Even our 13th month pay parang installment pag release- 50% on the day, 25% next week, 25% next yr-

So ayon nga gusto ko na umalis kasi ang unfair. I also heard na bawal daw mag apply ng same industry for 2 yrs so I have to find other industry for the meantime, so pano ako maggrow sa career ko nyan

Please advise
