First National Bank of Omaha Debt Collection Complaint

First National Bank of Omaha Debt collection department,

Credit card Taking/threatening an illegal action Threatened to sue on too old debt California

There is a company named - - - that continues to call me and threaten me with a law suit. They will not provide a validation notice and have made threats of lawsuits, coming to my place of employment to serve me, and stating that they will find me through my family. They have personal information about me such as my social and address and it concerns me. They offer a settlement over the phone and say I need to pay them through credit card immediately. This feels fraudulent and I am concerned they may be trying to commit identity fraud or collect debt that is not real.
