I upgraded my 7 Plus last Friday and have now had my X for a week tomorrow, however today I have had a charge to my bank account for one of the payments from my previous iup agreement. My payment date for my previous iup on my 7 Plus was in fact the 8th of every month however I am trying to figure out why there has been a charge today even though my agreement was settled last Friday as per the iup. Do you pay for the month you have used and not the upcoming month? Even if it does work that way, shouldn’t it be a pro rata amount as I traded in my 7 Plus last Friday? Bit confused and will obviously ask apple, just wondering if there is someone out there that has an explanation.
