There are two options.

You can buy coins. $30 gets you 300 coins, and you may be eligible to get a free package valued at $50 (lawl).

Or you can buy the premium rewards package. $30 would have gotten you 60 coins instantly, and for that you would receive new coins each week for 15 weeks. You can't get the bonus packages with premium rewards.

TL;DR: You paid money without reading anything. Ignorance is a whineable offense.
