Refund request from Capitec B819ank

I deposited R3500 and R1000 at Capitec ATM at Naledi Mall on Wednesday on the 7th April 2021.The 1st deposit was R3500 then the Slip cameback saying i deposited R2500 then the 2nd deposite was R1000 then the slip cameback said i deposited R900.I called the client care centre for them to help and i reported everyting having the both slips that i received from the Machine.I was given the Reference Number and they said they'll open an investigation and send people to go and check the machine.The'll call me after 24hrs which they didnt.i had to call them back again aftwr 24 hrs and i was told they'll call me on friday or saturday which again they never called so today which is Sunday i'm calling them to get answers to what happened to my case there not helping,I've been calling and speaking to different ppl now they just mute my calls or there not responding at all.That means i lost that R1100 just like that.no refund no explaination,no nothing.
