I just got a summons to appear in court from these guys (CCS).  I received a call from them last week from this number.  Do I have to make the court appearance?

Received snotty vm from ccs addressing no one in particular and no id other than ccs. HAD to call by end of day. Called back and got a very pleasant lady who said she had no idea what I was referring to and it was an investment firm.

Received a call form 714-975-7622. Alexis Anderson, from the office of James Crenshaw left me a message that I needed to return her call by the end of business today or their decision in this matter would be final! She referenced the road I live on and said it was regarding this property that I reside at and own. (I rent) The Phone # to return her call was 714 415 3592. 714 415 3049 is another number she has called from. She was very forceful with her message, now that I have read all of their scare tactics I can't wait for her to call me back! Oh, let the fun begin,,,,,

Idiots called me on a cell phone number that I have had for over 13 years. They are looking for the Asian gentleman that had the number before me.
1. I in no way sound Asian.
2. Any bills that would be owed by that gentleman would be well beyond any limitations.
3. I am looking forward to filing a lawsuit against this company if they continue calling.

My daughter received a cell phone message from CCC 714 975 7638  for me to call them @ 714 975 7622. I called and was "greeted" by James Crenshaw. He was "calling" to warn me of a breach of contract lawsuit that various companies have been trying to contact me about for 6 years.I have lived here so I guess they didn't look very hard. He did not tell me who this lawsuit was from. He did not have the name of the road I lived on. He started yelling because I would not co operate (my daughter heard him half way across the room). When I asked him to quit yelling at me and he didn't stop I hung up.
