During the months of XXXX and XXXX 2015, I started receiving calls for some unknown debt that the company admits is not in mine. I do not know what this debt is, or who they are looking for. The have continued to call my personal cell phone 15-20 times during this period. I have talked with someone at their company at least eight different times letting them know my name and that they have the wrong phone number. Each time, the person apologizes and tells me they will take my phone number off their list. I have received three calls this week alone. The company is I Quantify Management Services ( IQMF ) ; their number is XXXX
