this is not legit. This is a harrassment firm trying to collect money not owed to them by me. They have very sketchy info and start harrassing you. They know what they are doing is wrong but they will collect a few dollars here and there.
I have received quite a few calls from this number 469-220-0000. They go to voice mail, don't leave a message. You can hear a lot of noise in the background. I entered them on reject call now. They don't tell me who or what they want, I Don't answer. I find this to be very annoying.
