Used up my 5gb so now on 2g. I can't manage 2g so I refilled my account. However it seems it doesn't refill until when the first refill expires at the end of the month. Is there no way to restart it now? Do I have to wait until the end of the year. I'm new to this refill thing and when I went to my account it said I have $30 that will be used on the end of the month. Also during the purchase it said $100 refills last a year. So does that mean I would get a combined amount of $30 x 3 (300 minutes, 15 gb of 4g ) that last for a year or when done?
