Very Unhappy Client!

How can you want us to call the call centre's for everything but we wait for HOURS!!!!! Shouldnt you have more call centre agents assisting??? This is bad service...and when you go to the branches you are treated like you are there for a non essential service and given funny looks...yet due to a debit that went of i have NO money for food. No one wants to take the time to listen to me.... I have been with FNB since i was 17....im now 41...i have never once missed any payments and i handle my account exceptionally well...but i will be looking to change banks once this is all over....I AM GETTING SO UPSET!!!! HOLDING ON FOR SOOOOOO LONG and then told the reversal thing is not working...transfered to to team of bankers now but keeps going to voicemail...then rings and cuts off... how many times must i call in????? If this debit order that went off ends up being an UNPAID on my account....I WILL MAKE THIS INTO A BIG THING!!!!
