ABSA of its client stole my money , I dunno

Hello peter on the 19-07-2019 ,I tried to withdraw money from an absa bank AMT using a Standard Bank debit card , the ABSA bank machine did not give me the cash. When I consulted my phone a few hours later it showed that the transaction had gone through. I approached ABSA , they told me to approach STD Bank which I did , STD bank gave me a ref no and told me that ABSA was investigating , I was asked to wait 10 days for the investigations to be concluded on the 29-07-2019 I was informed that I would be credited on the 31-07-2019 , after the 31st when I did not receive the money in my account I checked with my bank (Std) they told me that ABSA declined the refund because they concluded their investigation and concluded that I received . They closed their investigation stating that their investigation was concluded, Today I approached the company where the AMT is and was informed that ABSA never approach them for any Video footage and if they had footage of any ***** they were suppose to inform that company so they could take action to protect their customers ( I am a customer there) . I think that either ABSA or its client using the ATM stole my money but they refused or neglected to inform me of same . They need to pay back the money, what you think peter .
