Bad client service

Firstly I would like to say Cell C agents are unprofessional, rude and require training. I received a black Friday special in November 2023 and my current contract ending 12 April 2024. I was told by the agent that the new contract will only start the end April when my current one ended. End of January they did not deduct my debit order when I enquired an agent told me my debit order was inactive when I questioned that she told me I need to speak to client services as she cannot see. I called client services and was advised to speak to collections however when the agent checks I’m billed for two contracts not 1, I tried explaining and asking questions regarding the outstanding amount she dropped the call. I called twice after that and the call was dropped again. No one is able to give me the answers I need as they referring me to departments back and for and dropping the call. I am so disappointed with Cell C especially after so many years I have been you client.
