Got this call which I didn't pick up, but made a call after it has been missed; as such weird nos could possibly be from telemarketers.  I made the call back and was confirmed that it was from the sales and marketing department in DBS, which I suspect, is another sales call for Direct Marketing products. 

The credit card application sent yesterday can't possibly be so soon; as I only sent out the mail after 5pm...if they need to call me, most likely it'll be during my ICT, which iPhone has to be with me as I don't want to be cut off from the rest of the world even during my military training.
