Pathetic security systems from ***** National Bank

Somebody hacked into my bank account and were able to transfer my entire salary out of my account without my knowledge. After reporting this and completing all the relevant documentation, the investigator only contacted me a week later. Nothing was done within this period. Only a week after submitting all the documentation have they started to investigate. After laying a complaint they contacted me and said that they are now investigating this and confirms that the money was taken **********ly, however they cannot guarantee that my money will be refunded and this process to determine whether my money will be refunded can take 6 weeks. It is obvious that their online banking is not as safe as it should be as these guys were able to transfer the money from my account without having the OTP? I entrusted my money with FNB just to find out that they cannot guarantee that I will be refunded. Surely they have insurance to cover such instances. My account was cleaned out, and all they cannot confirm when or even IF my money will be refunded. Absolutely pathetic!!
