UOB doesn't benefit its existing customers

Every time I receive an SMS from UOB regarding its promotions, I will feel that they are very keen to get new customers yet don't pay any attention to its existing customers. Based on their promotion, if I have $15,000 in my account, I should transfer $10,000 out and keep it somewhere (in other bank account) first. Then when there is this promotion, then I transfer the money back. A bit pointless right? =.=
