Worse network ever

I use to love vodacom passionately so, only used it ever since ,but now, i hate ever using it.I wanted to cancel my contract because I hv everything I needed. I explained that I only needed an offer that can bit 100GB at night and 100GB during the day for R349, and I was offered 150GB during the day and 150GB during the night st R249, only to find out it's home Internet, my money was deducted for two consecutive months for what I didn't sign up for, when I waited for my problem to be solved they signed me for a contract of more than R500 that I didn't sign for and am expected to pay for it, my contract was changed without my concern and am being taken from pillar to post since May.
