Green dot I attempted to make a purchase twice for $37 the purchase was declined at the time of payment.I came home and the money was missing for my card.  Nationwide

I called the company they told me that they authorize the payment and I had to wait until the 26 for it to return to my account. I waited for the 26 I called and then they tell me I have to wait for the 27th the 27th gets here and I called them and they tell me that I need to monitor my account and wait for the money to arrive. I don't understand why I should have to wait 12 days to receive money back on a payment that was declined at the time of purchase. why is this craziness going on why can't they just put the money back on my account .why am I waiting all this d**n time why they telling me it's be ready this day it'll be ready that day I don't understand what the problem is
