No because it was costing them money sending out paperbills. that's why they gave you the option to save them money.
now they will be keeping the money and saving money on top of that. if many people want the paper that was originally explained as a cost saving discount. and if they do charge extra as well as the extra people are now paying by the discount being withdrawn. then it will be obvious that they are profiteering from it.
having the attitude that "I won't make a fuss because.." is the wrong one Marty. you have to stand up for yourself and be counted. not lie down and be trampled on
