FNB how can we trust you

I am feeling really frustrated with FNB and so tired of explaining the same thing over and over. There is a debit order from Telkom (not my account) going off sometimes 2 times a month. I have stopped and reversed this countless time. a Month ago a consultant from FNB helped me with this issue,she assured me that it has been permanently removed and that it won't happen again,I was feeling happy again with FNB,till this morning when I received another debit order deducting over R2000 AGAIN. I cant despute or stop it on the app,I contact FNB but there was no consultant available. I really feel that my last option is to close my accounts at FNB and go to another bank. This is a very difficult time and on top of it,having a bank you can't trust with your money!
