7DAYS CANCELLATION IS A **** BY VODACOM

Good day

I did an upgrade on the 23 December 2020 which is for 20gb da,20gb night plus 10gb video play. I was advised that I have 7 working days to cancel my contract. I called Vodacom on the 1 January 2021 to request a cancellation, I was advised that I can’t cancel I need to request for a upgrade reversal I was provided ref no *** and *** that the reversal has been and that I can cancel but now I am not given my 7 working days to cancel. I am stuck on a contract for 30days that I don’t want.
