I just posted an article Maybank Premier Card Customer Service where I said I am more than satisfied with MBB and you on the other hand here not happy with their level of service.

Cash Deposit Machine all same lah, especially if you got like 99 notes to deposit, go try other banks' CDM and you will know what I mean.

It is common for MBB machines to be out of order especially on weekends and public holidays. So, I make sure I make payment on weekdays and always few days prior to the Due Date and save the hassle like what you mentioned.

As for you shooting the manager, aiyah, he's only allowing you to let go steam. But the fact remains that no further actions was required by the manager for your case.

And as for you complaining that you have to wasted money in HK, go get another credit card I personally never had any issue with my MBB cards overseas and most recent in Macau where I used my MBB MC  and did not inform CS I was going overseas too.

And you know what, the CS is correct, if you are not happy with their service, cancel the card. Why you still want to support them and want their plat card?
