It gets better......
By right there should currently be three chequebooks in
existence under my name:
1. The chequebook I got when I first opened the account.
2. The chequebook that got lost in the mail.
3. The chequebook that I finally got one month after requesting
(2).
When (2) got lost in the mail, I ordered the DBS operator to
invalidate it so that no one who finds it can make use of it. They
had definitely sent it out, because they had already deducted the
cost of it, and because they told me it had been
mailed out.
Now, another operator is telling me that the system tells him
that only two chequebooks are under my name.....
inclusive of the one that they cancelled. And they
had cancelled the first chequebook that I already have.
WTF?!?!?!? There should be THREE!!! So does this mean there is
one more chequebook out there, under my name, STILL VALID?!?!?!
And that their system is so f**ked up that they can give me
inconsistent information?!?!?!?

Seriously, just write a blunt email to the management or if that
failed, just write to the press and you will see it resolve
immediately
