Do not use Canaca.com, based in Canada! I have never used them and they keep trying to bill me. I've blocked them from charging my credit card, so we'll see how long it will take for them to try again. And their website and tech support phone is a phishing scam trying to grab your credit card and phone number without actually talking to someone. Good thing American Express has good customer service and can block a company from charging your card.
Just my PSA for the day.
