Poor Customer Service!!!

I withdrew cash from an ATM in Umlazi Mega City and a torn R50 note came out. I was told to go back to my bank to do a claim since I'm not an FNB client. I went to my bank and was advised that the piece was left in FNB's ATM therefore they could not help me with anything. Went back to FNB, spoke to 2 tellers, a supervisor and the bank's branch manager who told me it would take 14 days for FNB to refund me for a torn R50 note that came out of their ATM's. The next morning they call me to come to the branch for a refund since they found the missing piece in their ATM, something that I had cleary explained to them with 0% banking experience. How could 4 staff members including their senior not fathom the importance of client liason even if you are not part of their business. Why would I ever want to part of FNB if incompetence is their main thing!! Did anyone consider that petrol is expensive to drive up and down over stupidity.
