Terrible and Poor Service from Vodacom

I was Misled by vodacom consultant for a contract benefits to be loaded in my current Prepaid vodacom number. I was told that I would get 30G per month and I was only provided by 5 G. I called Vodacom within the Grace period of 14 days to cancel it and I was told it will be done within 72 hours.

Today is more than 2 months and Never been canceled. My prepaid number is Blocked now for *********** vodacom staff.

Fix this problem immediately as it is affecting me.
