Best Bank Missing Cash Deposit Atlanta Georgia

on 2/28/14 , my Husband went into Best Bank and made a cash deposit of $525.00, on 3/1/14, I proceeded to pay our rent, the monies was not in my account, I went to the nearest branch and was told by one of the supervisors that it was a Bank error and my monies would be in my account by  the close of the day. No monies was in my account. I went to the branch my husband deposited the monies in on 3/2/14 and was told that they never recieved any communication about my missing monies, the supervisor noted that the money was deposited but could not tell me what happened to it. I gave the supervisor a copy of  a email that was supposedly sent to the branch alerting them of my missing  funds, she reluctantly stated that they never recieved the email

I adamantly explained that now my rent is late and I have occured a $50.00 late fee, spent monies on gas twice to rectify this problem. She went on to explain that there has to be an investigation done, even though it was clearly a Bank error.

Why would the bank not return my money then do their investigation?

Poor customer service, Passing the Blame, and the customer is left holding the bag, of course I  plan to cancel my account. This is not the first or second time I recieved such bad customer service from this bank, without customers they simply would have no business.  

Warning if you thinking about depositing your hard earn money in this bank, Dont do it, its not worth it
