Complaint Review: Capital Management Services LP

Received a call from a man that yelled at me that i owed him 1,000 and I better pay up.  I hung up because i haven't taken a loan out.  Then my boyfriend  called him bac. He was harassing me so i couldn't talk to him.  So he called him, the guy told him" I owed money for a loan of $1,000" and wanted to know my attorney's name he also said "he had sent many letter to me at PO  box 77"  which I never received.   My boyfriend said she doesn't have one, then the man asked for my social which my boyfriend verified and then they wanted to know my bank name.  so i told my boyfriend to hang up and he did.  

I changed my phone number, closed my bank account and getting ready to change my po box.
