Coin Machine faulty

On the 29.07.2024, I took change of R 762.80 to Capitec Bank to bank it in to my bank account. With a girl assisting me she realised that the machine was "hanging". She got the key and opened the machine, she then closed it again. The machine started counting money from the previous person who banked coins. The machine rejected a few coins that she kept aside. We then tried to bank some of my coins to see if the machine does not stop in the middle of the deposit again. The first few coins went throug R130.00, Then R189.80, then R50.30, then R119.80 was taken by the machine but did not reflect on my account. We loged a call and receive a reference number #***. The coin machine rejected 3 x .50c and 3 x .10c = R1.80 (rejected by the coin machine). If you add up what was banked into my bank account = R495.50 + (rejected money) R1.80 give you a total of R497.30 Where did the rest of the R762.80 went to? R2665.50. The lady who assisted me loged another call for the balance of the money not reflecting #***. When I followed up on the call centre they could not see that there was any oputcome. I was told to go see my bank to see if they have received and mail explaining the situation. I feel that the bank should have contacte me to tell me what happened to the rest of the money. Are they taking money from people *******?
