New Contract with free BIS was a ****

In June 2014 I was offered a reduced subscription for R94 per month, starting 1st July 2014. I could no longer afford the contract I was on. Ever since this new contract commenced, my phone is de-activated on the last day of the month. I then have NO BIS service until such time as I go to a Vodacom branch to request re-activation. I have tolerated this for 7 months and every month your staff member assures me they have fixed the problem. On Monday I saw Happy at Nicolway who has reported the incident to remedy support. The previous month I was told to increase my monthly subscription to remedy the problem, so now I'm paying R220.09 which is not what I agreed to at the start of this new contract. I have taken the matter up with Consumer Protection. I cannot carry on like this.
