My Information Disclosed by DCA to a family member

I want to report an agent from Nimble group (KHANYI) who phoned regarding my WOOLWORTHS account and disclosed my information to my sister without confirming my IDENTITY, now I am humiliated & embarrassed . The people that did not have to know my business, now they know. I am not sure if Nimble group agents are educated enough about POPIA , if not I want Khanyi to be taken to training and her Collecting license be revoked by DCA as she clearly does not know how to treat Debtors personal information with dignity & respect . I want her information and the recordings of the call In place, to lay a complaint to DCA & CFDC against her, clearly she is not competent to be a collector , I doubt she went to training . At this point I am devastated as I was retrenched due to Covid & haven’t find a Job since then I sent my retrenchment letter to nimble Long time ago in 2021 ,when I was unable to pay my account, but they still continued to harass me & the account increased to a huge amount.After disclosing my account, they had went on to issue a S129 letter for someone who is unemployed & retrenched demanding me to pay the double the amount of money I owe to WOOLWORTHS. Nimble had Jeopardised my credit profile negatively I am unable to get any employment yet they want me to pay!! I pledge with WOOLWORTHS to remove my account from that company as it is unprofessional and de*****ing their customers . The management team or CEO of the Nimble to contact me regarding their rude & unprofessional agent (Khanyi )before I escalate this matter to NCA or CFDC so that they revoke her LICENSE !!
