*********** service received

Last year August I took a temporary loan of which I used to do it every month, and when the money comes in they will deduct on my account, the loan was left with R256 but they never deducted until I received a message on my app that I'm owing FNB I went to Rosslyn branch to find out what's going on Why am I receiving this type of a letter because I always have money in my account why didn't they deduct it,then a consultant who was helping me told me that they had a system problem I could pay it via app when I logged on I couldn't she didn't even offer to help me and they took me to the lawyers for their system problem their incompetence affected me, all I want to know is why did they take to the lawyer when they knew very well of their system problem they didn't even bother to send me an sms notifying me of the system problem, now I want to buy a car I can't because of what they did to me they need to sort this thing out I want my credit profile cleared otherwise I'm going to ombudsman I have all the proof that my account had money
