Contract upgrade earlier than supposed to

I upgraded my cell phone contract with Vodacom to a uChoose Flexi 110 contract with 500MB of data. The contract upgrade is supposed to have been effected on the 1st of July. On the 30th of June however i received an SMS stating the following:<br> <br> You have 4.00MB remaining of your data bundle. Without a data bundle you pay out-of-bundle rates etc...<br> <br> This was strange to me as I still had a month to month data bundle from my previous contract for 1GB supposed to be effective until 31/07/2015. My data usage for the day then came out of my R110 airtime instead of my 1GB data bundle.<br> <br> Also since my new contract has a data bundle i cancelled my 1GB month to month data bundle last month. This was done twice telephonically and once online. This bundle is still not cancelled and i was billed again this month.<br> <br> I thought they messed up the upgrade and will rectify it shortly. I was mistaken. I then phoned them to sort it out at which stage they logged a call to have my money refunded into my account.<br> <br> Then I received an SMS that my call was closed and that i need to go into a shop to sort this out. I do not have the time for that. Clearly you messed up VODACOM and you need to fix it.
