Both Letty and al63139 are dead wrong. I can't decide if they simply didn't know any better, or are purposely posting this useless information in an effort to dissuade others who may not know much into allowing default judgements to happen.
In any case:
al63139: There is no "club". You simply have to either have a lawyer, or know your rules of civil procedure. 'pleading your case' will do you no good if you do not follow rules of civil procedure like motioning for discovery of the documents pertaining to the debt in question and everything else JCMT said in his above post. Just not going to court is about the worst thing to do because even if they were able to properly validate the account, the judge would set up a payment arrangement you can afford where if you didn't care enough to show up then why should the judge care and just award a default judgement allowing the CA to then go after you aggressively...so that was not brilliant advice on your part.
Letty:
while it was a good idea to report them, it would not stop the court action. What you should have done was go to the courthouse and get the judgement overturned due to improper service, there is law in place just for this.
all in all that was not 'telling it like it is' because it isn't like that and doesn't ever have to be like that. There are rights and laws made to protect consumers from just such practices but you have to take the initiative and protect yourself.
