Vodacom *****

I have tried since MAR2020 to cancel 3 ****les - The vodacom sales people tried to - every call i was cut off the minute i said i need to cancell . I finally got hold of someone only to be told they have upgraded 6 ****les for another 2 years. I was informed i upgraded all of them in Nov 2020 . How on earth does this makes sense when ive been trying for 10 months to cancell them !!!!!This is ***** on behalf of VODACOM AND I STILL cannot resolve this . No where can they prove with an email that i asked to upgrade . VODACOM you need to contact me urgently
