?Missing money

I went to deposit money at Baywest mall on the 4 April 2022. I was assisted by a branch manager. He asked me how much am I depositing, I said 2 thousand he responded saying 1 thousand and I responded again 2 thousand showing him 2 fingures. The slip came out and I put it in my bag without checking. I was in a rush to write a test in the next two hrs or so. Boooom when I get home I received a call fee from a receiver, the money is shot. R1k deposited not R2k. I had to rush back. When I arrived I told the manager my story, he was not interested. I left the slip at home. He told me he can not assist me without it, not even a single apology offered. He gave me the paper with email address and what I must include to the email I must send. I was like huuu, its hardly and hour the least you can do for me is to verify wht am saying in ur CCtv and check what u can do because this money is needed urgently. My plea fell in deft eyes, I can not assist you without a slip. Mind you I told him the exact time of a slip print out. Because when I received that money short call I looked for the slip.

To cut the matters short, till to date I have not received any feedback. And no one bothers to call and follow up on my complaint.

Is this the write way to treat your customer?
