Constar Financial Services, LLC Debt Collection Complaint

Constar Financial Services, LLC Debt collection department,

I do not know Written notification about debt Notification didn't disclose it was an attempt to collect a debt Louisiana

I received a call today -/-/2018, the call was transferred from a colleague who said the caller said it was a recorded line and did NOT mention the name of their company. They did not call my cell phone at all because I pick those calls up. When i got on the phone he said it was a personal business matter, making me first think it was business, I work for a business and thought it was related to them, then he said my address and would I verify who I am, at this point I refused to and told them to NEVER EVER call my place of work again. At this point I went out side to call the company back and have tried to re reach him 3 more times and now he won't take my calls. All I know is the company name but no clue who they are OR why they would call me at my place of work. I was told from a few other employees that I've had a few calls like that but they thought it was about this business so they have hung up. My cell phone was on a do not call registry list. All I know is the company name. Constar financial .. aka " con '' sounds like a great company name. by the way.
