UNAUTHORIZED DEBIT

so i logged a complain with Absa about my account that i was charged for unauthorized debit order penalty fee which i dont have any debit orders on that account spoke to one of the ladys from Eyethu mall Orange Farm who called me and told me that they still investigating the matter its been over weeks now and i haven't received any feedback is that how Absa treat there customers when i was with FNB should i have any issues it would be resolved without me having to follow up am so unhappy with the service and i wouldnt even advise my friends or family members to join Absa they so unprofessional and dont take care of there clients i downgraded to a savings account and there was funds again charged and some presentation fee i just dont understand how this bank works am closing my account and moving to FNB which its way much better when i was with them i never paid R100 for a minus of R7.10 they would take that amount that am on a minus with done i never had a problem with Fnb nor other banks that i have used i thought Absa was better and the service was professional and the bank charges were better guess i was wrong with everything
