PITTSFIELD — More than two dozen people are back at work at Argo Marketing Group’s call center in Pittsfield.

The call center reopened on Monday, putting about 25 people back to work.

About 65 people were laid off in October when the center’s previous owner, Global Contact Services, closed it down after losing a major client.

Argo, which is based in Lewiston, tells WCSH-TV it hopes to double the staffing in Pittsfield by the end of the month.
