Vodacom Bad service

I did my online upgrade on the 3June and received the phone on the 4th June next day,I was assisted by Jennifer on the Online upgrade.on the 5th June next day called Vodacom to report that contract was not fulfilled there where missing things on the phone. the consultant promised to be delivered on Monday 8 June. That never happened for a week i followup and all promises and no one was helping.I called again to return the phone which was collected after 2weeks. and I requested a cancellation on my contract number ***, Account number: I*** and refund. Still on this day nothing has been done.I have called cancellation and upgrades more than 10 times but nothing has been recorded on the system. <br> online upgrade said reversal of dates take two dates to reflect on cancellation system. its more than a weeks, cancellation doesn't see the reversal, and they cant even get call notes that i have called so many times.<br> I have spoked to so many consultants, Mpho, Lungile Mkheda, from Cancellation, Jennifer and her manager from upgrades to name a few.I even was given references on the 2July was told they cant find it S3-8A52V-V0IUD. we are on the second month end nothing has been done
