FNB- MAKING ME PAY FOR THEIR MISTAKES

On the 27th of January I needed to withdraw nearly 10k from my bank account. I went into the Grassy Park Branch to do the withdrawal but due to their steep withdrawal fees of your own money and despite the steep monthly bank charges that you already pay it was suggested to me to increase my limit on my cell phone banking and then do the withdrawal at the ATM. The consultant was very helpful however the ATM's were given problems and I opted to then use the ATM at Pelican Park. I attempted to draw the money but it never left the ATM it did however leave my bank balance. I then phoned the FNB Call Centre who confirmed to me that they money was withdrawn and therefore left my bank account and I then had to rush back to the Grassy Park Branch to log an investigation which took 5 days to have my funds returned. Now although your staff was helpful this was a nightmare to go through. I never complained previously despite the fact that I urgently needed those funds for building material which has now been delayed due to me not paying the constructor on time. He also then increased the price by 2k due to me taking nearly a week to then pay him. My building project nearly fell apart. The constructor has no trust in me. YET FNB CHARGED ME FOR THE WITHDRAWAL THAT DID NOT HAPPEN!!!!
