I am receiving multiple, harassing phone calls from a company called XXXX regarding a scheduled service date. I have not received any documentation from this company and I do not recognize this company nor have I signed for any loans with a company named XXXX I have received multiple voicemails on my cell phone and they are also calling me at work and I can not receive these types of calls not do I want to receive these calls at my job. Someone name XXXX XXXX XXXX XXXX XXXX and a XXXX XXXX are calling me multiple times per day. Sometimes leaving a voicemail and sometimes not. They left a file number of XXXX but I have not received any type of written notice of debt or any type of correspondence from them but it sounds like they are attempting to sue me based on the threatening tone of the voicemails I have saved. They keep saying on my voicemail they need to deliver a notice of intent but I have no idea of who this company is. They left a number of XXXX. My cell voicemail does not identify me and this is in violation of the FDCPA and the XXXX.
