Received an unknown phone call from 848314? Answered the call to an automated voice stating that a charge of a few thousand dollars has been made on your UOB credit card ending in XXXX. Following that, it will give you options: press 1 to confirm the transaction or press 2 to speak to customer service.

As most people will not remember transactions, they will most likely press "2" to find out more. The call will then be transferred to scammers after that.

Wanted to share my encounter to warn others of this scam.
