POOR CUSTOMER SERVICE - MULTICHOICE

I have been a customer for 20 years with MultiChoice. I logged a query because my DStv is not working, and my account is paid up to date. The woman who answered to my query was very rude and asking me security questions including my cellphone number, which have change since I joined 20 years ago, and I can't even remember that number. My contact details and address were updated 4 years ago when I moved into my house. This woman should not work in customer service as she is unprofessional and absolutely of no help. After I informed her that I cannot remember the answers to the questions she is asking I asked her if she wants my HIV status too. She then dropped the call. This woman does not have any skills to work with the public or customers. I demand that someone with proper customer service training, knowledge and skills to contact me to sort out my account and connection as soon as possible. After this kind of treatment, I am considering cancelling my subscription with multichoice.
