Capital Processing Network Customer Service Issues

I have been using CPN for my business for years. Recently, my machine displayed a message instructing me to contact tech support. However, when I call the provided number ([redacted]), the call rings and then a recording informs me that due to technical problems, my call cannot be connected and suggests trying again later. I have attempted to contact them multiple times over the past three days with no success. As credit card payments are crucial for my business, I am concerned and seeking clarification on the current status of their support services.
