Contract without my consent.

I have 2 numbers with Vodacom. One is a phone line with data and the other is a data line linked to 2 SIM cards. January I run out of data on my phone. I check this during Feb and when I run out again, I query this to find that because my contract had expired in December, they took away 2 gigs of data and then decided to charge me almost 3 times what I had been paying. I then also find out that they did the same for my 5 gig data line, which had been on month to month for many years. My data cost increased tripled.

I complained and was told it would be rectified and I would be credited for the difference on Jan and Feb invoices. A few days later my data sims no longer worked, so I go to the vodacom shop to get the sims checked. Here I am told that I now have a 2 year contract. It has also been 5 days and the data sims are still not working. 1) The person that put me onto contract has committed ***** by putting me on a contract without my consent 2) Vodacom just changed the agreement without informing me and Charged me what ever they wanted to charge me. 3) Despite numerous complaints and me spending around 5 hours this week trying to get this sorted out, I still do not have a data sim that works. I am also yet to receive a call from Vodacom manager despite me requesting to speak to the persons manager who put me **********ly on these contracts

If I could, I would give Vodacom a negative star rating
