FIRST TENNESSEE BANK ATM MONEY DIDNOT DISPENSE MEMPHIS Tennessee

On 3/1/2017,I drove thru the atm at this location.The message that appeared was transaction cancelled,do you want to continue?My history  tells me,that this message means there is no money in the atm.That is when i normally walk inside.Thats what i did.But when i attempted to get the $300,message read insuffient.So went with a smaller amount.$200.It came out.But now the $300 is missing from my account.When i called my automated service,it told me that the $300 was pending.So i figured that it would go back onto my card by 3/2/2017,but it didnot.And this is where i stand today,3/3/2017,missing my $300.
