I think Maybank and RHB provide the worst services.
Firstly, most, if not all, of the staff there are not polite. When I want to apply for something like credit card, the staff there doesn't entertain me as if I want to borrow money from their father.
Secondly, for RHB bank, I applied one credit card because of its cash rebate for every petrol station in Malaysia. I applied in September last year (2008). I only received the credit card last month (February, 2009). The promotion already ended last December (2008). I don't think there is a reason why I want to use the credit card. So, I had already cancelled it three days ago...
Which Bank the lousiest Service.
