Worse Customer Service Experience with a Bank as a Client

On the 15.11.2022 I was withdrawing money on a cash express ATM in a garage then after the transaction was reported as successful by the ATM and i was told to take my card of which i did and after when the ATM was busy counting cash and it has already reported on my phone that an amount of R2500 has been deducted from my account load shedding strikes and the ATM went off and the cash was not reversed to my account and did not come out. I waited for few minutes on the ATM and the generator kicked in and once the ATM was back again and nothing came out and the ATM was operational and I immediately called Capitec bank and I was told of their investigation which they have to conduct and I was told I must wait 48hrs of which I did and after that I was told to wait 7 - 14 working days and now when I try to follow up as there is no communication of whatsoever I am told that the ATM I used was a SPARK ATM and my query will be resolved in 30days and why wasn't I told about that in the first place and I just want my money back and the way these consultant are talking over the phone shows that they don't even care about my frustrations and the fact that it was my last money I don't have food nor transport to work, This bank really gives shame to the word customer service and they don't even communicate and the consultants don't give me a straight answer they even refuse when i want to speak to the manager and now i have to run around for what is mine and why cant they speed up the process as some of us needs our hard earned cash and the load shedding is not our fault, why cant they speed up this investigation process of theirs because we are suffering and they wont compensate me for the suffering i am enduring because of this.
