Why charge for hard copy of phone bill?

I have opted for e-billing for my Singtel bill for years, without any issue.

Recently, I requested a hard copy of my telephone bill for a particular month, as I needed to seek reimbursement for a conference call made to an overseas line.

To my surprise, I was informed that there was a charge of more than $5.

Why is there a need for this charge?

E-billing not only helps save our environment, but also, logically, enables Singtel to save on the cost of paper, manpower and postage.

Surely, Singtel can pass the savings on to environmentally friendly subscribers like me, instead of looking to profit more from any requests for hard copies of bills.
