New contract wihc was not asked for

Vodacom called my mother who is in her 60s to ask her if she wanted an upgrade on her account for 15gigs of data. After refusing many times, the call agents became pushy (becasue they need to get their commision on sales I assume). They used great wording and convinced her that she wouldn't be paying more per month than she currently is. And that it is a great deal on the data.

This is pathetic preying on old people who dont understand these things. And mixing words around so it sound good.

A few days later a new sim card arrives are her door and at the end of the month she is paying an extra R200 a month for this data.

Then when she tries to cancel the "new deal" she is told that she can't do it in store and has to cancel via phone call. When doing this we were redirected in a circle to different extensions. Eventually getting to someone who can help us, then weare told she has to pay a cancelation fee for premature cancelation of a contract. Thats poor formVodacom.
