MIDDLETOWN, DELAWARE -- As a consumer from your state, I felt it was my responsibility to bring to your attention the following incident. I keep receiving harassment calls from NCO looking for collection for various people. I have told them this is a business and don't know who they are looking for. Have asked them to remove my phone # ** from their files but the calls keep coming. Please advise. As a resolution, I would like the following: would like them notified to quit calling my business and taking up valuable time of myself and my employees. Please contact me if you need more details regarding this incident.
