Cyber bullies are taking our money!!!! Nedbank is not doing anything about it.

So on the 7th of January someone got into my online banking and took my money. I called nedbank and did all they asked from the ***** department. Till today no acknowledgement of my email. I have been making calls trying to find out how far is my case still no answer. Their cyber security is pathetic. How does one get access to my money on online banking? At that time I am sleeping? Where was the other code sent and who accepted it for the transaction to go through? Nedbank I want my money it is totally unacceptable that till today a month later no one has contacted me. I am unable to use my internet banking out of fear that I might be hacked again.
