Dish Network took money out of my bank even though I've returned their equipment. $700 within a 10 day span. Nationwide

I recently had some unforseen circumstances that did not allow me to continue with my Dish service, causing me to break my contract leaving a $300 contract breaking fee. I was shocked to get an email letting me know that they were going to automatically withdraw the $300 within the next couple days so I did a bit of robbing peter to pay paul to make sure that the money was in my account.  Money gets taken out.  To my surprise, 5 days later (on a Sunday) I get an email that reads "Thank you for your payment" in the ammount of $397. My payment?!  Sure enough, they have now taken another $400 out of my account because they claim not to have received their equipment.  I call right away and give them the tracking number to the packages that were sent a week ago. They confirm that they have the package, but they're not able to refund my acount for another 3-5 business days.  In the meantime, my account is overdrawn and is racking up fees by the day.  If they have my package and they're able to take my money OUT in one day, why aren't they able to refund as quickly.  Who's going to pay my bank fees, and late fees for the bills I cannot pay untill my money is returned?! I did everything correctly in this situation. I payed what was owed, and apparently I'm paying for what wasn't owed. Do not use Dish Network, their fees are outrageous and they're not willing to work with you in times of financial trouble. $700+/- in less than 10 days, who can afford that?!
