POOR CALL CENTRE MANNERISMS

I called the call centre to enquire about a premium that went off and wasnt sure about since I thought my policy matured. A lady that I spoke to was very rude and at the end of the call she said "Yooo" and I disconnected the call. I then called again requesting her name because I need to log a complaint but Athenkosi told me that due to POPI Act he is not going to give me her name and I can log a complaint and then the call would be listened to. How is giving me an employee who assisted me's name in contravention of POPI?? Old Mutual needs to adequately train their call centre staff to handle calls professionally because saying "yoooo" to a client is just pure disrespect and very unprofessional. I need this to be investigated and the call centre agent's conduct to be addressed ASAP. I need feedback with an apology regarding this before COB today.
