I believe you are right about the Post Gazette. I also just cancelled my subscription a couple of days ago and they have already called here 3 or 4 times.
This call is calling at least 2-3 times daily and when I call the number back all it does is ring....No machine or person picks up!!! It is bothersome and harassing.
I tried the Erie Times number and they didn't have my phone number listed. I have gotten several calls from the 412 number mentioned above and when I answer, I get hung up on.
i have been getting the same things for weeks, this is after i cancelled the subscription to the Erie-Times News last May. I have filed a complaint with the attorney general in PA so i will let you know if i get a response. This is ridiculous, pretty much harassment.
