How do I respond to default that was filed & entered prior to the court filing my response?

Stanley Mosk Courthouse LA, CA Case13K06164 5/23/14 Plaintiffs request for default filed and entered 5/28/14 Response filed (Defendant) I'm a land developer. I owe landscape company $13,500. Contractor assigned his rights to collector, Glendale Acceptance, Kathryn Lauer. She is not an attorney. I've offered her a promissory note to be paid through sale of spec home. She's demanding $5k now and $15k in promissory note to drop legal case. She wants answer now or says shes going to file default with court (fax filing) I was not given written notice of the plaintiffs request for the entry of default which says she must do that at least 3 days before making request. I requested copy of form CIV 100 - she would only send 1st page of default but the 2nd where it she must declare if mailed or not. I need to seek relief from default judgement or not show failure to plead or defend lawsuit. With a default file and entered on 5/23 by plaintiff what do they need to do next to collect
