Dishonest Staff & Managers

I drew money on 28th October for R1000 and silly me trusting they have given me what I asked for put the money straight in my wallet and leave. Sunday I need to put the money away as I have stuff I need to pay, counts the money and they have only given me R800 so went back to checkers to question this and the Manger and teller are there assisting me. I did advise I was at fault for not counting the money but then again why did the teller not count either so was told they would check the cameras and of course to no surprise receive a phone call today advising that they have not got more than what was suppose to be in the tills. What I found very strange was that the teller said to me can I confirm, I asked what and very quickly she said to me nevermind and the fact that she remembered exactly who I was the next day was also rather odd due to the face that they see so many people throughout the day. Absolutely disgusted in the staff as well as the mangers.
