Aiyor...so forgetful lar...
I called UOB customer service to tell them I did not receive the statement and requested them to resend the statement to me. They told me I will be charged for the late payment but I can call to request to waive it when I received the resent August statement. I did ask for the amount that I need to pay and I paid it immediately after dinner yesterday. So everything settled and I will call to request to waive the late payment as soon as I get the statement.
Later that night, I found the August statement on my table, underneath/in between some books!! OMG, I did receive the August statement after all and I totally forget about it!! Hmmmm.... can I still request to waive the late payment, since it's me who forgets to pay it and not statement lost? hehe...
