In the old days, possible to forget the letter as manual
process. Today, computer management...no compassion, unlikely to
miss unless data entry error and auto data checks eg age. But
postal service may not be as reliable so letter can be sent out but
not necessarily received.
My suggestion is better to confirm. If one is intending to
pursue further studies, the worse case is they ask to perform
NS at the same time. Getting deferment for studies not as easy
once started. Also no issue with penalties etc.
They make human errors. The staff at CMPB are damn
careless.
That time I request for a follow up of my new medical condition
after I ORD-ed. Took them 6 months to process. Luckily it wasnt
urgent. =) The staff told me they are shifting their offices. And
their databases are messed up.
