FNB (*****s) Adding extra interest on account???

Dear FNB(*****s) Please note that you are caught *****ing money from people. My account last year was R17721,43. Today its on R19118,09 as confirmed with your agent who also advised me that for the last 10 months the interest was never more then R4 per month.... How the hell did another R1396.66 get added to the account? I know i didnt make payment on the account since last June but the reason is that I was umemployed. I got retrenched from work and i had insurance which paid for 6 months, then when i submitted the claim again for another 6 months as I was still not working (covid lockdown, hard to get work situation), they came back to me and said it was a voluntary retrenchment. WHY WOULD I LEAVE MY WORK TO SUFFER AND GO HUNGRY. Think about that!! Anyway, I wrote too many complaints and got nothing back and your workers are just to damn lazy sitting at home, not working like they supposed to becuase they are unsupervised. The service we customers recieve is **** as usual. I bet this conplaint will just go nowhere like the last few. Dont know why i bother but maybe it will help another person reading this. STAY AWAY FROM FNB. They more ******* then the ones high high up eish.
