DrugBuyers.Com: i received a seizure letter from customs

I know this is nothing new on here....I received a seizure letter from customs and was terrified for a week until I discovered this board and talked to some friends. This is my situation: In mid-August I ordered my first meds online. I didn't know a thing about it. I picked a random overseas company and ordered 2 benzos-a total of 60 pills.
Soon after, I regretted my order due to the cost and tried to cancel it. The company said it had already been shipped. A month passed and I received nothing. I began to pester the company about a refund. After several weeks, they FINALLY refunded my money. Then, in mid-October, I received a seizure letter from customs. The meds had not arrived due to a seizure, not because the company was untrustworthy, as I thought. I was all ready to respond the customs notice, but decided not to after many suggestions leaning more to that route. My question is this: Do I have anything to fear? I have stopped worrying about it, and have resolved to only order within the U.S. from now on (I've done that several times and had no problems). Did I do the right thing by ignoring the notice and do I need to worry at all about getting in trouble with the law?
