My question involves judgment recovery in the State of: California Alameda County

I am being sued by a company that I think purchased my CC debt from at least two other companies. I responded within 30 days of being served by a Processor. I did not accept the notice but he laid it in front at my door. I responded with a General Denial within 30 days of the papers being served. The papers were filed at the court on 03/01, the processor served them on 03/14 and I responded on 04/09. I received a copy of the Request for Entry of Default on 04/23 dated 04/20 saying that I did not respond in a timely manner. I would like to respond. I think I need a Motion to Set Aside Default Judgement. Is this correct? My trail date is July 16. What is the best course of action right now? I know I should get a lawyer but I don't have the money.
