Upgrade Department Gave Wrong Package

I was contacted by an agent to assist me with an upgrade, he gave me all the options & I chose one. When the upgrade was activated they gave me less data than what I was told the day I did the upgrade. When I called the call centre to query it & to ask to listen to the recording & to adjust accordingly, after days of being told we will get back to you, got a hold of someone that told me sorry we can't listen to the recording as the recording is too big for our system to be loaded to so we can listen to it!? So what is the use to have a call recorded for your protection & mine like the voice prompt says. I have since phoned numerous times & have been told that someone will get back to me till date no one has contacted me. Cell C just made that I can't cancel my contract as they kept on causing delays so I can't use my right to cancel the contract in my 7 days cooling period as per the NCA. I want someone to call me back today AFTER listening to the recording & give me some feedback! <br> <br> Seems like they never change their colours as my wives query of two years ago is also still not sorted even after getting confirmation that it was done! So let's see if history will repeat itself??!!
