Unjustified billings

Here are two letters on the invoices sent out by Singapore Information Services to businesses that did not subscribe for their services:

Based on my common sense understanding of the law, a business that send out an invoice without justification could be considered as cheating. They do  not have the power to impose a service on another party without the other party's consent and to bill the party for that service.  I hope that our attorney general's office will study this issue to see if any criminal offence has been committed.

I hope that they are not too busy studying how to frame a charge for illegal hawking against some people who sell the newsletters of political parties.
