The scenario:
March 10th I had $61.98 in my account. Using my debit card, I made three purchases in the amounts of $14.10, $27.36, and $18.99 for used textbooks (through Amazon, where you aren't actually charged until the seller is ready to ship). I did this after forgetting about a $5 lunch from a day earlier (there wasn't a 'payment pending' or 'hold' for some reason, like there usually is for such purchases).
March 11th the $5 lunch is posted. I was immediately charged a courtesy pay fee ($32). After the fee cleared, I still had $24.10 dollars to the good.
That same day the $14.10 payment goes through and afterward there's still $10 in the account.
Another $32 courtesy pay fee is assessed. Only after THIS point is the account overdrawn.
The other two book payments still clear on the 11th and then the 12th, even though the account is overdrawn and even though I never opted 'in'. Overdraft fees are assessed for both. The account now stands at -$132.20.
Because I wasn't declined for any of the books, I didn't know any of this was happening. And trust me, I don't have a problem with getting declined at the window, or in this case, by the bookseller. If I get embarrassed, it's probably because I did something to deserve it.
My plan is to talk to my credit union tomorrow morning and ask what happened. I clearly messed up by forgetting about the lunch, but no matter which way you shake it, unauthorized overdraft coverage fees sent my account spiraling, not a turkey sub. I'm willing to pay the fee for one of the charges because it was my own oversight that ultimately caused me to spend more money than I had, but that feels wrong since I never opted in and should have been declined for the very last charge I tried to make. I *would* have had enough to cover all but the last purchase, if it weren't for the cascading effect of premature, unauthorized overdraft fees.
The question:
Do any of you think I can rightfully dispute at least three of the overdraft fees? If my credit union is unwilling to concede, what options do I have? Who do they answer to about the new rules concerning overdraft coverage?
Sorry if this is posted in the wrong forum. I don't really consider this a numbers problem, but a consumer protection/faulty business practice issue.
