Paying for 2 packages

<p>I did an upgrade in July 2016 to Smart S. I was previously on 2GB Open Line contract. The new package was supposed to have kicked in 1st Aug 2016. Since saturday i have been calling vodacom to sort out my query. I have just been dealing with *********** people from the call centre. I called again on Sunday and Monday to put on a call limit and add more data, but i was told there's an error on my account/pending request. WHY AM I STILL ON THE OLD PACKAGE. THIS HAS CAUASED NOTHING BUT UNNECESSARY STRESS AND INCONVIENCE. I cannot even purchase data from the self help option or from the vodacom app. Am not being charged for using out of budle data. who is going to be liaible to paying this????????????? Vodacom has messed up and need to fix this. </p>
