Sent money from Chase ($8500) to a brand new Capitol One savings account. I had no notification or anything that it went through. I did another $8500 and that one got full notification. When I check savings account it’s $17000 and my account today is -$6500. I called chase and they put the stop charge one but I’m wondering if that $ will be reversed back to my account. I don’t have $17,000 so I’m confused on why it wouldn’t just get rejected. If anyone has insight or knowledge I’d appreciate it. Preferably a timeline of when I’d get the $$ back from being negative. Also would I be charged over draft fee’s for it?
