Vodacom accounts

A view months ago I manage to get my accounts as low as 900 because of tough times. Then I took a new phone for 1000 pm extra that give me 1900 pm. On the black friday deals they talk me into a upgrade on another contract and promise it would be a little more just for 3 months then would come down below the current amount. So I was expecting a account for 2000 but guess what THEY DID IT AGAIN my account is over 2500. Well this is the last time they took me for a ride. This people don't care if you are with them for a month or for 20 years.
