FNB something fishy

Dear Hello Peter Please assist me, I am tired of lodging this complaint,clearly FNB does not take some customers seriously. A few weeks ago I had contacted fnb for an increase in my overdraft, a consultant by the name of Palesa was assisting me, I asked her if I will be receiving the funds on the same day, she responded by saying only if I was pre-approved. She said she will do a scoring for me, which she did and advised me that I was indeed pre-approved, she read out the terms and conditions, of which I agreed to, she said the funds will be in my account in a few minutes. Strangely after 30 minutes or so, she calls back saying that the overtdraft was declined, she said that the pre-approved was for an old application. REALLY ???? what a lame explanation. I asked if I could speak to the manager as I was very frustrated, she said due to the current corona outbreak, she is working from home, however she will ensure that her manager calls me back within an hour, a day later I had to contact the fnb again as the manager did not keep his or her promise. She said the error was from her side, I do understand that as human beings we make mistakes, but she needs to take pride in her work and ensure that the matter is clearly sorted out, If I still receive calls from your call center telling me that I taken an overdraft and I haven't signed an agreement clearly this matter is not rectified,why on earth would I sign an agreement for an overdraft increase that I didn't even qualify for.Today 25 June, I was contacted by Karabo Morakane telling me that I haven't signed an agreement for an overdraft that I took on the 12th June,this error was initially caused by Palesa employee number- F***.I can't even sleep from this thing as its disturbing me. I had to spend money to go to an fnb branch to try and get this matter sorted out,guess what? I even paid off the initial overdraft that I had. My days with fnb are numbered, because you are ****** and ********.You are soon going to loose me as your customers,as I do not feel comfortable with FNB. sometimes my account is on a negative and a few days later its back to normal, I suspect money laundering is happening in my account, and before you contact me make sure that you read all the comments made on my profile,as I am not ready to explain myself again regarding this mess.I only had 1 overdraft for 2500 nothing else, and I have paid it off this afternoon. I spend money contacting your *********** call center and I also had to spend petrol to drive to your branch to fix your mess. I want my reimbur*****t, it is not my error, i don't know why it should be my expense. You always say how can we help you, instead of saying how can we stress you :(
