leaked my personal financial records

I had taken a loan from Barko loans Durban 1 and missed a payment, which I take full accountability for. however, this has only messed with my mental health and caused me loads of Anxiety. instead of Barko, chasing me up for the debt they have, continuously put my name down to my colleagues, not even my company hr office , no one has calls me to make a payment arrangement, cause of them chasing my co-workers up for my debt, I was provided with the number of the lady who helped me apply for the loan, where she wanted me to send her the money instead, when I requested for the company banking details so I could transfer the debt at the end of this month, she made a joke out of my situation , then I decided to email barko myself to make a payment arrangement myself, BARKO has leaked my personal financial information to people I manage and work with telling them that I haven't paid my loan not chasing me up for the debt but through people who dont work for them, I did not give consent for BARKO to have multiple people that I work with as my next of kin but every second person at work keeps telling me about my Barko loan that hasn't been paid, it is embarrassing and has made me lose all credibility with people, I work with, At this point I don’t even feel like going to my job cause Barko has leaked my personal financial records I have evidence of this both written and on voice recordings. This is not right as these short-term loan companies should not treat people like this. I am seeking further advice to take this matter further or they will keep treating people like this.
