Data Bundles not received

I phone yesterday to change my data bundles from 2 GB to 3GB since 2 its just not enough and the gentlemen who was helping me he said within an hour I will be able to use the bundles, but till now I haven't received anything, I was told that I would start getting the 3GB in January, but last when I phone in as at that time I was still using 1GB everything was change before I even dropped the phone, why is now I have to wait till the next month you might as well leave the 2 GB and the rest I will just have to buy, it just doesn't make sense and another problem is each and every time you speak to a different consultant they tell you different stories.
