The incident had more to do with you than the preacher. It was up to you to see that you had an alarm or means to see that you would be awake in time for your commitment. If you didn't mean to go when you went to sleep, you should have called. What does your word mean? How important is the fact of keeping your commitments to you? (Put the action of the preacher out of the room). Ask yourself, was I wrong? If I mean to be a person of integrity should I continue in the same way, or should I change?
Instead of making excuses, should I have said that I was wrong and apologized? Only you can answer.
After you have done that, you can then address the actions of the preacher. Did he have a right to be upset because you didn't come and didn't call? His service was important to him. Most people would certainly have said something to you about it.
Personally, where the preacher erred (in my opinion) was taking the matter to the pulpit. His conversation (in my opinion) should have been directly and privately with you. Many times we see the pulpit being used as a whipping tool. The person being whipped cannot respond or explain, verify or dispute factors relative to the whipping. besides, it is embarrasing, I imagine, even if true. (people usually know who and what the pastor is talking about)
After you have considered all of the facts relating to the matter, give him the respect of talking directly to him. If you didn't like it, tell him, not all the members. If you considered that you were wrong, admit that too. If possible, come to an agreement that you both can live with.

Still, it was all about who you are.
