Fnb Mall@reds service is bad

I am very disappointed at fnb mall@reds staff service I deposited cash into my account last week Sunday 6th December the money did not reflect on my account and since the bank was opened I was made to fill in a form by a lady on duty in the bank she assured me all.will be sorted by Tuesdays 8th latest. Guess what nothing happened.and had to drive to the bank again and I could tell.that my query was not dealt with I was interrogated by the staff member trying to assist me on what was I wearing which machine on and on at the end after waiting 1 hour and more I was told it will be sorted they will call me He called around 330 to say they have found the money it will be paid .Guess what no payment I had to call again Friday which was tou luck.that I went through because their phone is never responded to. Stanley i think its his name promised again it will be sorted and not sure why it's not paid Like really..today it's 12 dec 6 days later No money no update.i just need my money back that's all.The ATM took money I followed your process and have been patient but I can't anymore this is appalling

please pay back money if the staff don't know.wjat to do can they get someone senior and im charge to resolve everything
