Penalised for *****

3 Nov.2018 i awoke to an SMS R99.00 was deducted from my Cheque account. At 9.50 I called FNB and spoke to Sheldon was was professional and helpful, He said, "We had quiet a few calls regarding the R99 debit." I am being penalised R100.00 unpaid no funds charges for *****. i raised this and i was told he will make notes and in 3 to 4 weeks time they will get back to me. Happy New Year, 1 Jan. 2019 i awake again to R97.00 ***** on my account. I called FNB and ***** line the closed on public holiday. I try to reverse it via internet Banking i get a message, "Your Request cannot be process." I had to log it as cancel debit order yet i am not aware or authorised any of these debit orders.Now the first issue has not been resolved and now a second issue is her. FNB please correct my 1st and now 2nd issue as i ind it frustrating when simple issues cannot be resolved. Ex FNB Legal team manager.
