Rincon Management Services Intentional Representations on Uncollectable Debt Corona, California

I and my partner had a call from a man purporting to be from the Riverside County Sheriffs legal department.  He said that we were to be served the following day.  When asked what for, he gave us a phone number and case number.

When we called, a company representative alleged one of us owed $2810 on a Washington Mutual Obligation.  This debt was 10 years old and had be written of in 2003.  Collection was barred by the statute of limitations.  In addition to this debt we would be liable for court costs and lawyer fees.  To stop the summons we were to make a payment in the next four hours.
                                                                                                                                                             The representative said we had made a payment of $150 in 2006.  We had not.  She said the debt was on the Esperian Credit report.  It was not. We gave credit card information to forestall the summons, with the understanding that no charge would be made when we could show that we did not owe the debt.  The charge was made and further communication with the company was un-answered.  One of us is 85 years of age, and the other 64 years of age.
