I pay monthly for extra storage on both lines on my account. A few months ago I added a new line, and dropped one of the old ones, and just realized I am still being charged 3x per month for extra storage but only have 2 active lines on my account. The phone from the dropped line is broken so we can not turn it on to edit anything on iCloud and do not remember the password to log In from another device. How do I cancel the storage charge for the dropped line??
