FNB Premier : Useless service 37 days later still NO clue when my complaint is being resolved and who is responsible

So I am a premier client and have to say the services from FNB is absolutely terrible. I logged a complaint on 6 July 2018 after I took out a temporary loan in April 2018 and paid it up in May 2018 it was still showing on my credit report on 6 July 2018. I had to keep calling myself because I did not receive any feedback. I was told that on the 12th of July 2018 a manual update was done to rectifiy this and I need to give it 10 days to reflect after ten (working days ) I called back the problem was still not resolved but FNB did not even follow up they assumed it was resolved. The consultant just told me , mam there was a manual update done so we just have to wait. I then got hold of transunion and asked them from their side what is going on , the consultant informed me that there were numerous activation's and closings on this account from August 2017 when the loan was not even in effect as yet , I took it out in April 2018. It was opened and closed around 5 times but as of today still shows the balance due of R8736.00 which was paid in full on 28 May 2018. I called FNB back spoke to the complaints department who forwarded me to , premier suite who forwarded me to temporary loans who forwarded me back to complaints with NO resolution. Eventually I told the premier suite consultant that I will stay on the line and she finds the person im supposed to speak to as everyone sends me around in circles ! Eventually she came back and said she has asked the person dealing with my account to contact me urgently and gave me his name. When he called me back I told him what I found out from transunion and sent him a screenshot of my credit report with all the activations and cancellations before I even took the loan out , he said he would forward it somewhere. This was last week wednesday. I called back on friday morning to find out what has been done , he told me it was sent to the back office marked for urgent and could not tell me anything else , what is being done how long will it take etc. Again i just have to wait and hope someone looks into it and gets back to me! I need someone of authority to look into this and give me proper feedback between FNB and transunion there has been some kind of miscommunication and this needs to be sorted out !! ITS NOT FAIR that FNB didnt even know about this issue before i informed them and let it drag out so long ! IT IS OVER TWO MONTHS SINCE THIS loan has been settled and still I am sitting with the issues
