Empty promises, terrible after sales service

I called the Vodacom cancellation department in February 2016 to cancel my contract. I was assisted by Megan Camp (stationed at Midrand). After inquiring as to why I wanted to cancel Megan offered me 100 Vodacom to Vodacom minutes every month for 24 months as well as 1 Gig of data every month for 24 months, this offer was additional to the minutes, data and smses that I was to receive every month with my package.I was also downgraded from Smart S (which package I was on for 2 years) to Smart XS, less data, less minutes for the same price as I paid for my Smart S package.I was ONLY informed of the downgrade AFTER the phone was ordered and about to arrive at my doorstep.I have not received the 1 Gig of data for the month of April 2016. I called customer care on 1 April 2016 to inform them, I called again on 2 April 2016 as I had still not received the data. I called again this morning, I even tried to contact Megan but for some BIZARRE reason no agent could connect me to your Midrand branch.Sending me from pillar to post is an understatement.I am being charged OUT OF BUNDLE rates for something that is NOT my fault.I will cancel due to breach of contract if this is not resolved.
