Primus phone company charges $25 for invoices

I'm a Canadian who just switched my long distance service, not because Primus charges too much for phone calls, but because I consider one of its service charges to be ridiculous. I had not received my invoice and called the company asking that they fax another one. I was told there was a $25 charge for a duplicate invoice. Suffice it to say, I paid my bill without seeing the invoice and immediately switched phone companies. It's not only gauging to charge so much for a faxed piece of paper, but it's also a stupid way to do business. Doesn't the company realize that the sooner a person has an invoice, the sooner they're likely to pay--and once people have heard about the $25 charge, they'll probably put off payment until next month's bill arrives.
