Soooo... you "worked" for SL for three years and you don't know any better than to update your credit card info when you change credit cards? And now you call SL "The Mafia"???
Dude, you are SO in the wrong, here, and I sincerely hope LL gets wind of your post and bans you for the "almost" threats you've made here. How anyone in SL for three years and not know to update their credit card info is beyond me. I've only been a member for about 6 months, and I know better. You got what you wanted. You come in here and pitch a b**ch about getting $L when you got EXACTLY what you paid for. It came out of the "wrong" credit card, so what? LEARN from YOUR mistake, update your card info. and enjoy your $L.
Placing what seems to be somewhat "threatening" responses to LL/SL about this situation when it's clearly YOUR screw-up, NOT LL/SL's isn't going to get you much (if any) sympathy. At best, it'll get you banned. Seems you may not have a complete grip on how to do internet business, and blaming others for your short comings isn't going to get you anywhere. Take the help you've been offered, do what you can to straighten out your "honest mistake". LL just might work with you on this, if you calm down and keep a civil tongue. Do what's been suggested: make a call or two and see what happens. But putting a stop on payment for services already received just might land you in hot water.
All IMHO, of course!
