Well,since my 1 month Xbox LIVE trial has expired now.So,I want to continue my account for only another 1 month,this is because after 1 month+plus,I need to go study already.I live in Penang,it is hard to find the 1 month LIVE prepaid card,so I decided to buy through my console using my dad credit card for Singapore Dollar $14.90 per month.OK,here is the problem,after 1 month,I need to go study already,I wont play Xbox 360 anymore because I not at home,so,is it that time Microsoft will continue keep charging my dad for another month(long term)?So,if we want to stop the credit card from charging by Microsoft or bank,what should I do?
