<prompt> Human: This morning I was trying to book 500 air travel on Deltas website, but they declined my debit card. I didnt know why, so I thought Id try again later with my credit card after my bill was paid today. This afternoon when I checked my bank account, I found that they had posted an 8,000 charge to my card anyways, putting my account 4k into the red. Ive tried calling Delta and my bank multiple times. Delta says they have no record of the charge, and my bank says they cant file any dispute until the charge finishes processing after 2-3 business days. So, Tuesday. But this is more money than I have and I cant wait until Tuesday before I have to buy food. This also happened before my credit card bill went through, so now that is late as well. No one is offering any help and I dont know what else to do. Please, do you have any advice?Assistant: It is still processing, meaning that it will post a different amount most likely later on.Human: Sure, and hopefully itll be no charge at all because I didnt buy anything. But Im still not able to do anything with money until then, and apparently I just figured out that Ill be charged 35 a day in overdraft fees until then so this will be even more fun to go through.  <response>: If the charge doesnt post, you will not be charged an overdraft fee. It will be like it never happened. What you have here is a 4 day issue. You can manage 4 days without access to your checking account. Even if it did charge, when you dispute the charge hours later, the entire amount including any overdraft fees, is refunded until it is resolved. Everything is assumed in your favor until proven otherwise. Please just chill and figure out a way to beg or borrow for a couple of days. This is not a long term issue. Oh, and other posters are right. This is the main reason to never, ever use your debit card for online purchases. Errors effect you much worse than some theoretical charge on a credit card that hasnt even been billed yet.
