Called my work, big no no!!

This person was rude and wouldn't tell me who he was he asked for a name of a person with whom I don't know and he called me a liar.

I too just got a call from them about a debt from last year.  I did not recognize said debt and asked several times if I could have something in writing to show where it had come from.  The gentleman got loud and said that they would sue me and it would be on my credit report for 10 years, also the 300 dollar debt would be ballooned out to over 2k when they finished with it.  

The man I had spoken with did not have my current address (been here since before the "debt" happened) nor did he have any other info except my name and phone number.  I asked at least 5 times for the information in writing and he refused.  Totally sketchy situation.

763-432-6013 called but left no message.  Looking at other posts it came from Bridgestone & Associates.  A representative from that company has contacted me several times claiming I owe a debt to a company I have never heard of.  I asked for documentation and he offered up a "demand letter" stating that the only way I can receive it is by fax because they do not use USPS.  The caller belittled me and was shouting so loud into the phone I had to hold it away from my head.

This number 763-432-6013 continues to call my company cell phone - which I've had for over 4 years now!! Previous number belonged to the individual they are trying to track down... I've told them every time that I am not that person, nor do I know them and this is a company cell phone number now.
