Unprofessional service from Lungi

I have been dealing with Lungi from Vericred for quite some time now, being a debt collector agent does not mean you have to be rude. Today at 26/08/2021 11:47am Lungi called me with private number, 1stly that's a red flag for me, 2ndly it was like she's with her friends as they were laughing at the back, so unprofessionally, her telephone etiquette is very bad. I wish you could listen to her our recording. I have been paying the account through Durban University of Technology she did sent me their account details since the account is no longer with DUT. I told her I am not able to load vericred account details on my app it always give me error and she had no solution for that, told her to update my account by getting statement from DUT that the account is being paid I'm not sure if she did that. That woman is rude and I would really request my file to be transferred to someone else who will treat me with dignity and be professional
