As of now, I have Public Bank Quantum MasterCard and Visa Credit Card, with the credit limit of RM 16000.
If I correctly remember, the minimum credit limit of Public Bank Visa Signature Card is RM 35000.
As suggested here, one way to get Public Bank Visa Signature Card is apply for lower level credit cards (such as Quantum Cards), and slowly increase your credit limit till RM 35000 (with your payslips showing increased salary), and request to add a Public Bank Visa Signature Card.
Here is my dilemma. The maximum spending amount for me is RM 1200 per month (RM 600 for Quantum MasterCard; another RM 600 for Quantum Visa), just to get the maximum cashback of RM 30 for each card.
So, after I get salary increase and submit the payslips,
how can I convince Public Bank Credit Card Department to increase my credit limit to RM 35000? After all, I never spend beyond RM 1200, let alone RM 16000 of credit limit originally assigned to me.
I know that Public Bank currently has 0 % balance transfer, and 0 % FlexiPay. But, I prefer not to use balance transfer and FlexiPay, as they may lure me to uncontrolled spending beyond my financial ability.
Thank you very much for your kind suggestions.
