It's been few days trying...

Directly call to bank branch, nobody pick up.
Call to 1-800-22-5555 nobody pick up.
Call 03-2179 5000 nobody pick up.
Email to customersupport@publicbank.com.my never reply.

Seriously, worst ever customer service

I don't think so, even if that's the case they should set an automated message in hotline informing customer about the interruption.

Yeah their online banking website looks and use like those vintage website being done in the 90s. Not only that even the internal banking processing has stupid problem, I remember paying my loan installment in the last day of the month and the transaction already done and shown in the loan account but then their system still auto debit my current account and pay to the loan again meaning double pay in that month

Same thing today...

I swear I will never ever deal with this bank anymore when I can refinance my existing loan.

Reported profit every year but never try to improve their core business. Probably the whole bank just riding on past success and gazillions of mutual funds.
