No No No add on

I received a call a month or so ago to advise on contract migration. I called back the next day and advised I do not want to change my contract & i was advised that that my contract will remain the same. I called again 2days ago as I see on my Vodacom app my contract has been migrated whereas I said I do not want it. Then I receive a sms thank you price plan change & another sms saying thank you for the insurance of R9,99 I TOOK incase of death then my contract is paid - I did not consent to this. I have not given consent to migrate my contract nor taking up insurance of R9,99!!
