I was never a UOB retail customer. Maybe many years ago I have taken their home mortgage before. That time I was staying at my old address Last year, I signed up with UOB One credit card with my new home address which I was staying since 2012. Only few months ago I was trying to sign up with their internet banking so I can check my credit transaction only. To my surprise I couldn't do so, the customer service told me the UOB bank itself still having my old address. I was very unhappy because I signed up the card with new address and UOB sent me monthly bill to new address for the past many months. I just simply cannot apprehend this simple logic. What the hell! Time past, only 3 weeks ago then I walk in to UOB Bedok branch to fill the form to update my new address with UOB. I have ticked the form to update all my accounts. Few days later, then I received the letter from UOB saying my address is updated. Then I happily to register my internet banking, the system failed me again saying I don't have the card pin. So unhappily I called the bank again request for the pin. Today, I received the card pin by post. Again, I happily try to register for the internet banking. To my surprise the system failed me again saying my address is not updated. Then I speak to customer service, instead of helping me, the customer service wanted a screenshot of the letter I received from UOB on the address update. I was very upset by her request. This is a letter from UOB, why she is representing UOB wanted a copy from me? I told her she needs to get this internally and don't be lazy. And I wanted her to resolve this by tomorrow and get back to me, but she refused and she told me she needs 3 working days. I told her I don't need her service as she couldn't help me much and she transfer me to another customer services after I waited for many minutes. The new customer service only speaks to me for a short while and then the line cut off. He didn't even bother to call me back. Terrible UOB.
