Relentless calling from a company called Portfolio Recovery and they call from several different phone numbers and I have called every number that they have called me from stating that I am not the person they are looking for and that I do not even know the person they are looking for. It 's to the point now that I just pick up the phone and hang it up because it is pointless to keep telling these people I 'm not who they are looking for. This is my work number and it is getting very aggravating dealing with them calling XXXX times in an XXXX hr shift.
