I won't accept any NP-1 ... reversing charges on a Credit Card is very easy... I gave them that back in JULY ... zzz ... if they charge it... it shall be reversed :-D was $699 back then... or something like dat ;-)
BTW and FYI, and not to throw a damper on your good time, I'm reasonably certain that charging something to your credit card with the intention of reversing that charge when it occurs is probably not strictly legal.
I know. I'm just a killjoy. It's a curse.
No. Trying to reverse charges after receiving and keeping property would be frowned on. Changing your mind before getting a service is not illegal. Never has been.
