Poor Service

Hi I have been trying to get a through to Cell C 084143 for days now. When I call their call centre they will keep me on hold for more than 20mins then someone answers they go silent then I get through to the rating service option. I've called their Customer Care all they do is transfer me back to 084143. I've been to the store and they referred me to the 084143. All I want is to cancel my contract. I've called on the 7th of September they gave me ref *** to cancel however to my surprise nothing has been loaded on their systems regarding my request to cancel this contract. It's really frustrating and poor service no one has an interest to assist
