M1 has replied!

We refer to the letter "Can't recall wife's birthday, so no help
from telco" by Mr Jimmy Ng Kim Kok (March 11). We express our
apologies to Mr Ng, on the distress he had encountered over the
possible roaming charges that may be incurred.
After his report on the loss of his wife's mobile phone, we
suspended the line within 10 minutes of his call, and after further
review and verification.
M1 undertakes strict operating procedures to safeguard the
confidentiality of our customers.
In the event of unforeseen circumstances and should there be an
inaccurate response during our verification process, we will review
the request prior to taking further action. Letter from PETRINA
TEOH, Senior Manager - Corporate Communications, M1 Limited

In other words, all his rants on TODAY newspaper was for
nothing.
If he had just calmed himself down and called M1 again, they
would have simply told him that the line had already been
suspended.
Heck, I get the feeling that the Customer Service Operator
actually wanted to tell him 'Okay sir, never mind about
your wife's birthday, I'll talk to my manager, and ask him if we
can just suspend the line anyway', but could not do so
because he had already hung up in anger. 
If anything, he will now face the wrath of his wife for
forgetting her birthday and for having the smart aleck idea of
announcing that to the entire nation.
