FNB poor service

I app**** for a personal loan at FNB, On Monday 14/10/2019 the amount were paid out, together with two additional amounts that i did not apply for. I immediately transferred the amounts back to the loan accounts, as i did not want or app**** for the loans. The next day, i contacted FNB loan division, and the agent advised me they will reverse the initiation fee, for these two loan amounts. AN hour later, FNB reversed all three loan amounts, and left my account in a negative. I went to the FMB branch in Cape Road, Port Elizabeth, and the most unprofessional, unhelpful staff I've ever seen in a company. I've been trying for the past week to get this sorted out, and the only feedback i receive is "its been revered" I currently have loan amounts on my account, i paid penalties on my cheque account for a negative balance. I'm receiving threatening messages regarding my "over draft" . The best part is, when ask to speak to someone that actually knows why they work at FNB, I'm being told I'm not allowed to speak to management. I'm done with FNB, and if this is not sorted out tomorrow, i will take this to the news papers.
