Vodacom complaint

I am livid about the account I received for the bill of the Rooter (R635+). I was offered and agreed on the following: 1. 20GB day & 20 GB night @ R299 2. This amount of R299 including the connection fee of R85 would ONLY be deducted in November. 3. A promise of NO ACCOUNT CHARGES FOR OCTOBER! I am a Vodacom Client for years and this is the first time I have had such poor service. Since I received the Rooter: 1. it took days to be connected, 2. DATA DISAPPEARED within days! Vodacom is not delivering the service they offered.
