Hmmm,
interesting. And from a link in there,
we see this.
Is it legit? Could be.
However, I would first ask your credit card company and warn them about charges, that you don't want them, nor do you accept them.
Next time you get a phone call from these people, ask to see the actual bill. The details. Not just a text file saying the Prince of Nigeria requires you to pay, not something in an email chain, an actual proof of money owed. Ask for a picture of the violation. Have them send it registered mail. And tell them until they provide that they must stop calling you.
Do not provide them with an email address, everything through Canada Post mail or courier.
Although on the site it says that you can dispute the charge by offering proof, that's just bogus. It's up to them to provide proof that you owe money. If you're skeptical, how about that $450 you owe me? I'll sue if I don't get it.
If they do charge your credit card which was supplied by the rental company, dispute it immediately.
If somehow this turns out to be real, make sure you get in writing that the dispute is resolved and that it won't be on your credit reports. And if they can't agree to that, why pay?
