This really isn't a big deal if you use credit card policy to your advantage.
When I canceled a subscription to a local paper (Dallas Morning News), their policy said I had to call to cancel. Instead, I sent an email informing them I was rescinding authorization to charge my credit card.
They initially responded stating that I had to call to cancel my subscription. One more email reminding them that charging my card without authorization would be credit card fraud turned out to be enough to have the phone call requirement dropped.
