How to recover my Mobile Legends account since submitting form don't work

I cannot log in on my ML account because it requires a verification code, but unfortunately, I cannot remember my password on that Gmail account either and I lost my phone number I use on that Gmail account.

Hello Moonton, sincerely I want to replay again the mobile legends but cannot use my mobile legends account as it requires me to request verification code from my Gmail account but sad to say I do not have access to that Gmail account and also the number I used in that Gmail account as I misplaced it. I only have access on my VK account, which is linked to my mobile legend's account. Can't remember all the details on my mobile legend's account because it's already years since I started trying to recover this account. I've provided all the purchases, models I used, and date it happened. Still, nobody has replied at your CS.
