<human>: Condense the text into a few key points

So, I'll preface by saying that I know procrastination has bit me in the ass a bit here. Just to get that out of the way.

On March 21st I received a Civil Action Hearing Notice from a MDJ in Lancaster county. In the Civil Complaint, the plaintiff describes purchasing a horse in August, 2015 from an address in Lancaster county from a person who has my same exact first and last name. The complaint goes on to describe a violated contract regarding refund for the horse, travel expenses, expenses for "tracking down <my name>", and court expenses, all totalling $1,775.00.

I have never lived in Lancaster county and have certainly never sold anyone a horse, so I know I can't be the correct/intended defendant. The plaintiff's address is in New York. The defendant's address is mine. 

I know I should have called the court about this immediately or tried to get in contact with the plaintiff to let them know about their mistake, however I haven't done it yet. The hearing date is this Wednesday, April 20th. I'm going to call the court first thing Monday morning to see what they say, however I'd like to know what is about to happen ahead of time. I'd also like to know just how much I've screwed myself by not taking care of this sooner.
<bot>: I'm being sued but I'm not the person the plaintiff intended to sue. Court date is on Wednesday, I haven't called anyone or done anything about it yet. Wat do!?
