Upgrade gone wrong

<p>i did an upgrade with the Vodacom 4 u shop in mall of Africa on the 4 of march 2017. I have no realized that I shouldn't of upgraded my contract. I should of rather cancelled and moved to prepaid. I have had endless problems with my contract and now they told me that the contract that I took out was only available to clients on the 7th of march. So I need to just stay with the package that was available at the time. The consultant then tells me that she will buy me airtime to accommodate for the mess up. That don't fly with me. </p>
