Anyone heard of B and M Group?

Hello. I was wondering if any one has heard of B and M Group. The number is 1-877-441-9874. Today I had Erica Wilson call me at work to let me know that she was a processor server and was coming to my job or home this afternoon. She gave me a reference # and a phone number to call. The first thing I did was call my court house to check if there was anything in my name. Of course there wasn't. Then I called the number and spoke with a Michael Burke. I talked to him for a bit and told him I needed something from the company in reference to the pdl. I told him I didn't want an email or fax but something sent to me via usps. He then asked me to hold and someone else came on the phone. Could not catch his name. He was asking me really stupid questions and I was laughing. So he hung up. I did ask for a fax number and he refused to give it to me. So if anyone knows anything about this place and can provide me with a fax number, I would greatly appreciate it.

By the way the call started I knew they were not a legal debt collector. I am tired of people calling me and thinking I am a fool.
