Bad service

I experienced a bad service at nedbank I opened business account at nedbank around sep or Oct 2018 I was helped by Leon Naidoo. I deposited 500 but I used it again as I was expecting cash in that account unfortunately it went to my private account then I transferred 400 into my account. Same October I went to the bank and as I needed a confirmation letter and internet banking I was helped by Leon who gave me the 2nd account and I didnt see that it's a different account. Few weeks later I received an sms that states that my account is overdrawn and it doesnt say how much I transferred 50 rand then it showed me available of -27 rand then I did a 20 rand. This month i was expecting 182 000 in my account because i dont get smses I went to the bank to check if I got paid all to find out I was on a minus 217 i immediately called nedbank and I was told that my account was closed they were so rude to me and I was told to go to the bank and sort it out there they can't help me. I asked about the 2nd account unfortunately it was also closed . On the 12th of December I went to the Nedbank in southgate yes my account was closed and I was advised to call Leon and find out what the problem was I did that , Leon advised me to deposit 300 in my account I did that then he told me that he will call me back after few minutes he never did and I told leon that I'm expecting money in my account. The 182 000 bounced back the same day. On Friday the 14th I called Leon again and he told me that he doesn't know how my account was closed and he asked for my deposit slip I did send it to him , still he kept on promising to call me and he never did I called him after 14:00 , he never picked up any of my calls he never bothered to call me back. On Monday the 17th I called him and he told me that the matter is with his line manager and he will call me after receiving feedback. On Tuesday I called Leon again and I told him that my money bounced back, he asked for an invoice that shows that money was transferred to my account. I did send it to him, still he never got back to me . On wensday I made a call again around 11am and Leon told me that he will give me a feedback at 13:00 and he never did until I called him again after 15:00 he never answered my calls. After about 30mins I received a call from him and he said they refused to open my account. I've never experienced such drama I'n my life such a lie from my banker. I believe that if there was something wrong with my account Leon was supposed to be the 1st person to see if there was something wrong. He was never an honest person promising lies . I asked for his line managers number he didnt bother to send them. The sad part is that now I have to go and work again how will I work without money in my account. I dont wven have 6months with this account but already it's been closed. This is unacceptable
