How can I get overdraft bank fee's refunded?

I was charged for multiple overdraft fees. The first for overdraft, $29 and second for everyday the account was overdrawn ,($3 a day, was 10 days overdrawn = $30) Total for $59.

One of the reason i didn't have money in the account was because one banker at the bank told me I could not transfer money from my business account to personal account (the overdrawn account) without writing a check, .

In my first attempt to get a refund I spoke to 3 people from the bank. It's bank in the US.

The first person told me there was nothing they could do, and while i was explaining my situation, hung up on me. (-1 for them)

The second person, said he could only refund $15 and would ask his manager if i could get full refund and would email me the manager's response. Have never received a response for them. (-1 for them)

The third person I contacted was a previous banker I worked and told me he could only refund a small amount and would have to ask his banker. He was also the guy who said I couldn't transfer money from one account to another, which out writing a check. When i contacted him, he then changed and said I could transfer from business account to personal. He then told me he would have to ask his manager. Since my deposit was negative, he transferred enough me to make it positive, then , he said he could refund the $29 dollars but would still have to ask his manager, about the other $30, because it was an error on my part not theres. I explained that it was an error on theres because he recommended me not to transfer from account to account.

So right now i want to get my $30 back. So far in this process that have lied to me countless times, are not trying to admit error, and hung up on me. In addition, on there website they claim that the reason for the overdraft fee is too avoid customers the unpleasant experience of not having enough money, when in reality this is a far worse experience.

With all that has happened what steps would you take in getting this overdraft fee refunded? Thanks
