From document services. Tried to get me to call another number. Won't send anything via US Mail. Tried calling number but it is disconnected. REALLY???

Left ridiculous messages stating a complaint has been filed against me. When I called the 888 number back the rep asked for someone I have never met. I explained that I do not know the person and demanded they remove my number from their calling list.  Nevertheless, they are still calling daily.
