Cheque theft

Hello, I recently deposited a cheque from my boss into my account via the ATM at Absa at the Pick n Pay centre in the Bluff on the 24/11/2018. The cheque reflected In my account with a notice of it taking 10 working days to clear . On the 28/11/2018 my boss got debited with the cheque amount but on the 03/12/2018 there was an "internal reversal " done . I went to to the branch asking them why was it reversed . The clerk informed me that they did not find the cheque hence the amount got reversed . Even though the amount got reversed it was not credited back into my bosses account and I also have proof of depositing the cheque . The clerk called today saying they still cannot find the cheque and I should ask my boss to rewrite another cheque . Why would my boss write me another cheque if I have proof that I deposited the cheque and especially since he was already debited . The problem is with the people that are working within the bank and handling the cash/cheques at the ATM . I have been given the run around the entire week with no joy . Absa owes me the money!!! Your assistance in this matter would be greatly appreciated.

Kind Regards
