Call in The Next Ten Minutes/ Denying the Antecedent.

Hopefully you get that those TV commercials that promise that you will receive something extra if you call within ten minutes, will still give it to you even if you call later. One reason is that there is usually no way they know which ad you’re responding to. And if you reply that it’s illegal to lie in commercials, I’m forced to tell you that you don’t understand fallacies as you don’t get that if “x implies y” it doesn’t mean that “not x implies not y”. So, they are technically not lying.

No further explanation needed. All comments welcome.
