How do you prevent customers' cheque(s) mailed through Post
Office from going missing?
Blank Envelopes. Banks send their correspondence to their
customers with unlabelled envelopes (without bank name or
logo). Why is that so? I believe it is for security purposes and to
prevent double work from lost mail or post man with malicious
intent.
Unhappy Customer. What if disgruntled competitors /
customers / others threw away the customers' mail? If customer
did not receive the credit card statement and the bank send
another chaser one month later, asking for late fee. How would
you feel if you are the customer?
V for Vendetta. It may be true that if someone have a vendetta
against an organisation with millions of employee, they may work
for the post office to discard letters bearing the organisation
name / logo?
