Upgrade frustrations

I upgraded my contract on 24 March ***. The upgrade was agreed as follows 125 minutes airtime, 10GB data for 24 months at R69pm. What was actually activated is 125 min airtime and 500megs data. I am being sent from pillar to post by the call centre including being transferred to Elite Mobile??? Can I please get an answer as to why Vodacom is not honouring the agreement that was made when I upgraded. I suggest you listen to the upgrade call before you contact me.
