Nedbank had taken my money and I can't do anything about it, they then treat me with disrespect and display total incompetence in doing their job

On the 15th March 2021 I went to nedbank to pay my medical aid for me and my daughter as I am a single mother, I paid by the ATM and once the money was in it told me the machine was faulty so after I waited a while I went inside to query this incident (my mother waited by the ATM incase it threw my money out while I was away), once inside I was given a query number and told I'll be contacted, they sent me a sms saying my query was declined, without a explanation, I went in to the bank again and once again same story as before, I was met by rude staff who were too tired to do their job and discussed me in a very rude manner with his colleague in Tswana in front of me, thinking I can't understand what they are saying, but I could... Eventually after the 3rd time my query was declined and I went to the bank I was told the money was paid into the medical aids account and was given a proof of payment, with out the recipients account number on it... My medical aid declined this proof of payment because they said there is no account number so they can't be sure they were the recipent of the transaction (I did give the guy at the bank the account number 4 times at that point), nedbank carletonville said they won't provide me with any other proof and bonitas medical aid said they won't accept it... Finally nedbank wrote a letter for me to send my medical aid with the proof of payment they gave me saying that the payment was made to Bonitas, which my medical aid refused to accept once again, when I told this to nedbank they shrugged their shoulders and said "tell them to stop being difficult"... Its been 15days since I made the payment and I've gone 15days without a medical aid that I paid for... My daughter is starting to get sick which leaves me in a predicament because I'm a single mother and my medical aid takes a big chunk of my pay and since I've paid it, I don't have money to pay a doctor now too... If I could change things I would never have banked with nedbank to begin with, their customer service is atrocious, I've called head office who apparently can't help me, the manager I want to speak to in the branch is apparently always too busy but I watch her everytime I go there, sending voice notes and laughing away at her phone so I doubt she's busy with actual work... The team leader I'm referred too is conveniently never there... So who do I talk to? Because apparently nedbank hasn't got anybody assigned to this kind of thing? From head office down to the tellers, nobody is qualified to help me - so it seems... I urge anybody who reads this to stay away from nedbank, they are apparently allowed to take your hard earned money that you put in their hands with confidence, they can take it without reason or explanation and then tell you it's not their problem, they can't provide proper proof of who they have paid with my money or what has been done with it, they refuse to refund me too, so putting my money in their ATM means my they can claim my money and I can't do anything about it, my money has been ****** by this bank and they have basically told me I can't do anything about it... That's how this bank treats customers who put their trust in the bank with their financials, they slap you in the face.. And when you ask why, then all the relevant people aren't available or nobody is qualified to help you... Nedbank should be ashamed of their carletonville branches low work ethic, poor manners, outrageous incompetence and rediculously poor service... Nedbank taught me a lesson, and have lost a loyal customer in me, after being chewed up and spat out by the bank... I hope nobody else has to go through such demoralizing treatment from their bank or anyone else for that matter.
