Received a pre-recorded voice message purportedly from UOB regarding a credit card transaction of a few thousand dollars. To speak to a Customer Service Officer (CSO), I was instructed to press 2. The CSO identified himself as Wong. I requested his full name and number for a callback. He reluctantly stated to address him as Mr Wong. When I asked for his full name, he hung up.

Be careful of such impersonation phone calls.
