<prompt> Human: Last year I decided to use my Amex instead of my debit card or cash, to improve my credit. Id spend something like 1-2kmo and just pay it off. I noticed month after month my statement was always big so I stopped using it because it was getting hard to follow if a purchase was this month or last. I havent used my amex in 3 months but my mom still has one. Her transactions are less than 500mo but for the past 3 months my statement balance was 1-3k. I pay the balance off every month WHERE IS THIS COMING FROM?Do credit card companies have anyway of showing total purchases and total payments for an account or is there a 3rd party service, like Mint, thatll do it? I really didnt grasp account in college, despite being great at math, and I dont understand how spending 500mo would yield a 1k statement 3 months later.Assistant: I noticed month after month my statement was always big My guess is mom is actually spending more than 500 a month. There is a transaction history for our account. It should be accessible online. That will let you total up all the credit and debits to the account. Human: Ive already done that. Amex shows transactions by cards. If you look at mine theres 0 transactions the past 3 months, looking at hers shes only spent about 2k in the past 3 months yet my last 3 payments have been 2k, 2300, and 1750. Ive also noticed recurring charges, disputed and canceled, from a lost card last August. I see the transactions on the statement but doesnt show under either cards, because its a lost, and canceled, card and I even disputed these transactions and was told canceling the card would prevent them from recurring.  <response>: Call them.
