Useless un helpful manager

I Upgraded my router to 5 gigs. My contract was changed. So I dont get night owl data anymore, I never asked them to change it. I have been in and out of Vodacom store for the past four months and nothing has been sorted out. I have wasted my time and petrol going to sort out this problem for no reason. All because some useless manager changed my contract. I want this sorted out this week. The 20 gigs of data owed to me I want plus I want my petrol and my time paid for. I did not ask this useless manager to change my contract I was upgrading it.
