Business ProfileforMonarch Recovery Management, Inc

Monarch recovery Management has been repeatedly calling me for the past few months. I drive for a living, and I work long days. I always try and answer my phone while working, in case its a customer with a problem. Unfortunately, when its Monarch, I am unable to express to them that I do not do business over the phone in those regards. I've asked repeatedly for them to send a letter stating what debt is owed, signed by someone within their office, as up to this point, I have no idea who they are and who they claim to be collecting for. The last time they called me (yesterday), I was driving down the highway, and I asked them again, to send a letter and I stated I do not do business like this over the phone. I informed the person that I was driving and unable to talk and he began telling me its not a sales call. He kept going on about whatever he was calling about and I informed him I was driving, to which, he didn't seem to care. I got frustrated because I'm moving at high speed trying to be aware of the conditions around me, while also trying to focus on where I was going (on a delivery), and trying to listen to him. I finally told him I was filing a complaint with the **** and hung up on him. To this date, I have no idea who Monarch Recovery Management is, but I would like them to never call me again.
