This company calls me every other day about 3 times a day. I answer and no one speaks. The only time someone was on the other end said that I had a bill in collections. When I asked who the bill was from I was placed on hold and no one ever came back. Hard to pay a bill when you don't know what/who/where to pay. . Interesting enough, I have not received a statement nor do I know where I owe this money to. Im reporting this to bbb and my credit agencies.
