LTE Data not accessable

<p>I have a data bundle of 50GB. I am supposed to get 30GB LTE data for the first month of my contract (30 days)<br /><br />My billing month starts mid month. </p> <p> </p> <p>My cellphone activated on the 28th November 2016. I was given a nominal amount of data. on the 13th December ( at which time I had only worked out that this was the billing month) my data and airtime was cleared and new data / airtime was added. </p> <p> </p> <p>On the 27 November 2016 20+Gb was removed from my account. I have only got 1.7GB left now to carry me through to the end of the month.</p> <p> </p> <p>I assume that bundled data is used before promotional data. This in my opinion is not fair. It is not explained in contract. I now have limited data to carry me through to 13 January.</p> <p> </p> <p>I have used 30GB of data out of bundle. I would like that data to be reinstated.</p>
