This is a collections company, but a shady one. Called me several times, but the last time I answered (at 8:00 at night). Woman on the line was getting mad that I wouldn't give anything other than a first name until I knew what it was about. She kept saying "Receivable Management Services, a collection agency." I still wouldn't budge until she finally said who she was collecting for (Republic trash services). I bet she was still mad when I still didn't give any info, told them never to call this number again, and hung up.
Just got a call from them this morning. Dude was obviously in India or Pakistan. Could barely understand him. Wanted personal information and claimed it was debt collection from some company I've never heard of. Yeah, right.
