I was served a summons and complaint by a process server but I said I was not the person he was looking for and didn't know that person (even though it was me) and he gave me the papers anyway. The Papers do not have a court file number nor a case number. It only has a case type listed as consumer credit contract (3A) and there is what appears to be an attorney file number. Papers are from Rausch Sturm and they say I need to respond with answers within 20 days. The 20 days will be in 5 days now and falls on a Sunday. What is my best action to take? I'm in Minnesota. Thank you.
