dept. of law and investigations claiming that a company named cashnet marketing is ivestigating me for being fraudulent on a loan that i suposedly received from them. long beach, California

i was repeatedly harassed over the phone by this company. The person that kept calling was named,so he says Officer Phillip Sheehan. He constantly left threatening messages on my voice mail. The messages were ,"This is regarding a serious legal matter that has been filed against you. You need to respond to this call immediately, and if you do not respond then may god help you following the outcome. You need to contact me immediately your time is running out. You donot want to ignore this serious legal matter. When i returned the call Phillip asked me all personal information, address, phone number, social securty number, the bank that i used whether or not if i had closed out the account. he repeatedly told me that my address,phone,and social security number were under investigations. He told me that a company called cashnet marketing filed the suit stating that i had received a loan from them and did not pay it back, and asked me if i had an attorney and told me that their company had atleast ten attorneys concerning this matter. I told him i never received a loan from this company. But i had received one from cashnetusa and that they had been paid in full.   So he claimed that he needed to speak with his supervisor regarding this matter and his supervisor's reply was that they would get back with me after they recontacted thecashnet marketing company and updated their paperwork. Iimmediately called cashnetusa and they confirmed that it was a fraudulent call. I called Phillip back and told him that i was told by cashnetusa that they were fraudulent, Phillip didnot come to the phone but had someone that sounded just like Phillip, but said that Phillip was his supervisor and that he could assure me that they were not fraudulent and he again contact cashnet marketing and give them this new infomation and would contact me as soon as he did this.
