No VOIP Service

I reported a loss of VOIP service, and when there was a response, it was several days later, with a silly question. By the time I responded, they had closed the ticket and I had to start again. I resorted to using the live chat WhatsApp service, but there I too kept being disconnected because no agents were available. One agent eventually provided me with configuration instructions, which did not solve my problem. My further queries were not answered It seems nobody is listening.
