Poor service experience

On Sunday morning the 8 March 2020 I went to spar mall at Bluewater Bay Port Elizabeth to deposit money at Capitec ATM while the machine was processing my transaction the machine canceled my transaction and retain the money with out any deposit receipt and I reported the matter to capitec call Centre with reference number ***3 I was told to wait for 48 hours for the bank to investigate but I need the money now to pay my creditors, is this fair practice for the poor clients and the lady assisted she ask me how much I deposited? She disputed that I deposited R1500 she can't see the amount she only see R800 and r780? Am so stressed because this is the third time this happen to me this year at capitec bank. Can Capitec sort out this matter as soon as possible please. I need my money to pay my creditors.
