WORSE SERVICE EVER!!! SICK AND TIRED OF THE PATHETIC SERVICE!

I am sick and tired trying to sort out an issue with my account since 2017. I e-mail them all the correspondence between myself and them with the proof of payment and the reference numbers with cancellation. They insisting I owe them R956 after I received an e-mail that they infarct owe me R554. Now they handed me over to a collection agency who contacts my family regarding this matter and when I contact Multi choice to speak to a supervisor they disconnect my call. I am fed up I e-mail I call but no joy
