problem with overdraft fees

I got a really big problem with my bank (Wells Fargo). I accidentally put a wrong check into my account, but I didn't know so I was spending money like usually. The next day they put this money back (because of course it was a wrong check). I totally get that, but because of that I came into the negative. At the same day I went to the bank and gave them the right check, so I was in the positive again. Now a couple of days ago I got overdraft fees around 150$ and I was in the negative again. So I went there back again and they told I will get that fees back. Now that still didn't happen. Their system is showing up that I got this money back. But the really weird thing is, that it doesn't match with the money I had and spend and also not what I can see in my mobile bank account. They told they can't do anything, because the computer is showing it up like that. Is there still a chance to get that money back?
