CHICAGO (CBS) — Complaints about cable companies are legendary, but an online rant against Comcast on Wednesday got a response, and revealed a little more about the company’s practices.

Wednesday afternoon, Rev. Michael Pfleger took to Facebook to complain Comcast had told St. Sabina Church it could not send a technician out to fix Internet service at their employment center, because of violent crime in the neighborhood.

The post was shared hundreds of times, and five hours later, Pfleger posted that Comcast showed up after his complaint drew attention from social media and news media.

A Comcast spokesperson told DNAinfo Chicago the company canceled the appointment at St. Sabina, and five other appointments in the area, after Chicago police warned them about a possible spike in violence in the neighborhood. The company said it was looking out for the safety of its employees, and rescheduled the appointments for Thursday.
