XXXX XXXX of Northstar Location Services ( XXXX ) is continually calling our phone number looking for my sister in law stating they are collecting a debt. We do not know how they got our number & my sister in law knows nothing about this. I e asked them to stop calling, to remove our number to no avail. I looked the company up & I see XXXX complaints. Please do what you need to do to shut this down asap!
