vodacom has ****** my data

<p>I upgraded my contract for which i recieved my phone beginning of May. I was told that the contract would kick in from the 1st of the next month. My previous contract was a data contract. I still had 1G left during the day and 2G left for the night. I have been told that the new contract migrated over on the 31 May and my internet usage took the airtime for this new contract. WHY was the contract not migrated over as all contracts do from the beginning of the month? I wanted to use my last 3G 0f data and was unable to do so. To make matters worse, Vodacom alleges that I used my new contracts airtime on the 31 May. When in fact the last time I had used my ****le was on the 30. Please explain and credit me for my data. this is *****ing</p>
