Bank fails to own up to its mistakes

On the 17th of December 2015 standard bank returned my disputed my salary back to my employer. I called in minutes after I received the sms I called in standard bank's general banking and had to hold. A lady picked up and made me hold even further for help. I was unhappy with how long I had to hold for such an urgent matter. I was then promised to be called back for feedback and feedback never came...the next day I called in and still, standard bank fails to sort out the issue. I was advised to take my statement to my HR and my HR was happy to help, however, it's gonna take at least 21 days for my employer to send th money back to my company. I've tried logging complaints with the bank and it seems no one cares. They don't even care that I've been without my salary for so long. Standard bank has wronged me yet doesn't want to compensate me. I've decided to take legal action and sue them...it is as though my rights as a consumer an human being mean nothing to them - they really have shown me than as consumers we are but tools for them to pack more money in their pockets so they have lavish lifestyles
