<prompt> Human: On my Discover card, I cannot account for 96.21 between 624 and 710. Last time I reconciled, I couldnt account for 33.31 on this same account, except then my records were showing 33.31 more, while now Im showing 96.21 less than Discover shows. This only happens with Discover. Our Citi, Capital One, and bank accounts never have any issues. What would you do?  <response>: You know this, but Ill start here: sometimes theres a lag between a posted charge and it appearing on the bill, so I go through them item by item - and Ive done so with the card co. on the phone. Maybe theres something you missed - maybe they made an error.The other thing I picked up on is that theres a discrepancy in the interest charge - how much theyve charged over what period of time. Some of these card co.s get _really_ creative with how much they charge.Give em a call. In my experience, Discover has exceptional customer service. Even if its an error youve made re: interest calculation, e.g., they may waive it or some of it. When I first took over a relatives accounts as Power of Attorney, I was able to get a lot of fees and interest waived.
