A Fuming client thats hates being unecessary broke

I am a client of FNB since 2004, I have not have issues with charges up until now. Before I buy I check my balance and buy then get an incontact stating that the amount has been deducted and then tells me how much balance I have. The 1 scenario I went and deposited R850 from their atms deposit, I bought at Spar for R224.48 and the balance was R626 including the R10 or so I had in my account, I then transferred the outstanding amount from the savings pocket to ensure R639 for the online purchase I made. It went through and I received the incontact stating that I have R1 or so change left and the transaction was successful. On the 6th of June the bank reports that I have -R110 because they honoured my transaction as I had R560 something, on the norm even if I am short of R0.20c it declines and I have to pay the R8.50 charges.

On my account the bank states on th e9th of June that I have -R156 or so and then a deposit was done of R2500 which I still didn't understand what do I owe, then I buy as per usual check my balances before I buy etc, I buy online for R367 last weekend the 8th or 9th of June and have 100's worth of change and bought from shops etc, the incontact tells me funds have been deducted this is the change on the app. Up until yesterday I get an incontact that my account is in excess and at -R165 for what God knows.

I cannot keep my funds without owing, and if the account is at R11 balance I owe R150 or R165 etc all the time. Even if I have R100 avail it goes on a minus, the part that ****es me the most is that my app updates per transaction immediately even buying R5 airtime and states the balance. How the hell am I always owing, all the freaken time. I am sick of not having money on my account, my account doesn't let me buy if I am short, then why the hell doI keep on being on minus and so convenient when there is little funds. I buy on a Monday, system deducts and a week later I owe.

I always have a good word to people about FNB even tho people complain about them, don'yt use the damn bank no wonder they have the tallest buildings and fancy ish because they take and take and blames someone else.

I need to know why the system tells you one thing and a week later it tells you the oppm, why deduct money and tell me the balance after that particular purchaser and days later I owe, I am no freaken accountant but I can read and the app reports.

Tell me what the hell is going on, I have never had this before why now
