Bad communication & bad service

Again I am completly amazed with the bad service with Vodacom. Since August I have been waiting for them to come and collect their goods. They finally collected the staff beginning of December. After that I heard nothing from them when they are going to refund me .They keep billing me no one says anything about my money they are taking especially the rooter I was never able to use I want my refund and I want to cancel this contract for the phone and the rooter
