NGL, I keep logs of that shit and I get a real boner doing a charge back about how I don't approve and then when my CC is like why, I send them the documented proof of a company's fuckery. Timestamps, who I spoke with, how I did due diligence in trying my best to cancel but the shit hole company made it a hassle.
Did it four times in a decade and not a single rejection from the CC to get my money back.
