TELLER ERROR

On 29th April 2015 I deposited R2010 teller accidentally entered as R210 I then went back on 3May15,Kurt(branch manager) took all my particulars said will get back to me. <br> <br> There was no feed back so I went back on 5th May15 where I met Assistant Branch Manager (Reagan) who showed no care he told me they haven't heard from G4S but sent an email to them asked him if they don't have any cameras as the teller counted the money in front of me he said 'no'. I then laid a complaint via their call centre on 6May with this reference no:***6 an agent Yoliswa said to wait for 48hrs till to date 9th May 2015 I haven't heard from them.<br> <br> Is it possible for a bank not to have cameras at their tellers? How long does it take to count money's in banks?
