Cash Call/Unified Portfolio Servicing

I live in Ohio and took a Ioan from Western Sky in 2011. Shortly after taking the loan it was transferred to Cash Call. I defaulted on the loan in 2012. Today I received a call from a unified portfolio servicing who stated they got my number from my county court office and will be filing charges against me for check fraud if I do not make a huge payment by end of day Monday. They said in addition that my bank account would be frozen and i would be placed on the checks system so I couldn't access my bank account or get another until this is taken care of. I've read a lot about the legality of cash call and am wondering if this company is legit and if I should be arranging payments with them. I have not gotten anything in writing advising of this and I'm not sure how they would get my phone number from my county court. has anyone had this happen to them ?

western sky is tribal,and them plus cashhcall,and delbert are getting slammed all over the country.debts even legal ones are civil matters at best.they didn't get your number from anywhere,but western sky/cashcall.report this piece of garbage and ignore.
