Chase review: I was shorthanded $1000 while depositing $7000

Then I handed separate 3 different stacks fo money and verbally communicated amounts. The cashier never physically counted the cash I handed her, only used the money counting machine but never communicated to me the total. The teller counted each increment individually; I could not see the total displayed anywhere At this point there was zero communication that the increments were different than what I handed her and communicated to her. She told me to look at the pin pad for the total and press the green button while she put the money into the large money counter. The screen displayed $6,000. I immediately told her that was not the correct amount that I gave her. She said that the money was already in the machine, and she could not take it out to recount it in front of me. I asked the manager to recount money, but they only performed an audit of the machine. I requested to check the cameras to see where the error occurred but was informed that can't be done. The lack of professionalism, transparency, and honest business practices. I am used to teller always counts the money by hand in front of you as well as with the machine for a second layer of verification and communicates the total prior to taking the money behind the desk. Was that a machine error or employee theft I want justice to this case.
