Bad service not taking ownership of their mistake

On the 26th I withdrew R3000 at an Fnb Atm in Ronderboult Spar, the Atm gave me R1200 of old R200 notes which was part of the R3000 withdrawal. When my wife went to pay our electricity bill she was told by this vendor Municipality official that they don't take the old R200 notes anylonger. I went to Fnb Sunninghill branch who told me I have to take them to an Fnb which is closer to where I made a withdrawal. I went to Fnb branch in Boksburg where their supervisor told me I should take the notes to Reserve Bank of which l expressed my discontent as it's non soever my mistake. They told me about their rules and procedures of which the question is how much of these notes did they distribute to the public through this Atm? There is some serious lack of customer service and care which has really left me considering that about my relationship with Fnb.<br> <br> Looking forward to hearing from you.
