My question involves collection proceedings in the State of: Utah.

So I just got a court summons about 2 hrs ago for an old credit card debt. All the courts are of course closed because it is Saturday, and I figure I should deal with them rather than calling the company suing. The Statue of Limitations in Utah for Credit Cards is 4 years (as far as I can find online). I'm pretty sure this debt is older but I'm not sure. I haven't heard from them in years actually. It was a Bank of America cc account, but the company suing is a collection agency in NY (Calvary Portfolio, LLC). Does anyone know how I can find out when exactly I defaulted and the SOL clock started ticking? Or am I just going to have to wait and talk with Calvary? I appreciate all your help.
