Data contract

I had a contract with them around june of data and rooter which i had to pay R160 upfront and was told that i will have to pay R360 monthly, within 10 days of using the the data , they switched them off and i was told that i have to pay R486 which now includes some insurance which i didn't know off

I tried to tell them to cancel my contract since it wasnt what i signed up for , but it wasnt a success

Fee days back i received a call saying that i owe them 2600 and my case have been taken to some legal teams
