FNB seems unprofessional

I have been using fnb for 6 years now and many of my familly members as well. Only family members using fnb have been ****med or attempted to be ****med by someone into giving up their details, yet no one from Bank Windhoek. I lost every cent in my account due to this issue, but besides the way, when tryng to call fnb emergency line I could not get through to stop any transactions and had to get a new card for a reasonable fee at least. This makes me believe that my information is at greater risk if I am a fnb client. Also I have been unable to withdraw money due to error code D055 with the new card and I am simply not able to sort it out via fnb.
