No feedback on quey

On Monday 25.10.2021 i was at FNB Newton Park Port Elizabeth to make a cash deposit into my business account. When I left my home I had R8700, I then deposited this amount at the ATM. The ATM confirmed R8600. I then walked into the branch to ask the ATM custodians to investigate. I even said to the lady, I could have miscounted, but still I would like it to be investigated. The lady(Noxolo) stated that the lady that works with the ATM can only check the following day, of which I was fine with that. She took down my details. On Friday 29.10 I went to collect my debit for an account I had recently opened, I engaged the lady who assisted me with the card collection (that was an opportunity to remind her colleague of the query coz at that stage it was still a query). She was dismissive because I was trying to explain to her that her colleague said I was going to be contacted on Tuesday, she just told me about 3-5 working days TAT, and ATMs are done externally, I assume by SBV, today is the 7th working day, it is now a complaint. I still haven't had feedback regarding my query.
