Disappointing Customer Service

I purchased this app quite a while ago and loved it for quite some time. However, in the last few months, I have not been able to view PDFs saved within the calendar. I understand there can be bugs that need to fixed, so I emailed Public Folder support to let them know of the issue. After emailing approximately six times in several months, I had never received a response. I even mentioned in my last email that I would write a negative review if I did not hear back in hopes that I would at least get a response acknowledging the problem. But I have heard nothing. I am disappointed in the customer service.
