lying to get sales.

A Vodacom agent called me, saying that I'm on a 20GB day and 20GB night plan, but people are complaining because they are not using the night data so vodacom is changing it to 30GB day and 20GB night for the same cost of R219 (going back i now remember i pay R200 not R219) my one question was would the contract term stay the same as i dont want it to start over he said yes it will remain as the original) We then went ahead. later i got a email and the contract is a new 2 year contract. I want this cancelled. I do not want my term extended. also listen to the call and send me a copy aswell. FIX THIS
