Pathetic after sales service

When I initially app**** for the fibre line I was extremely impressed as, after my online application, I was contacted within a matter of minutes to arrange an installation date and my line was up and running within a few days. Later I started having billing issues and unauthorized line upgrades and charges. Today I was trying to manage the users on my line and the online portal shows the feature, but it shows no devices are connected to my line. When I click on the usage tab, there is no history whatsoever. I tried the "LIVE" chat feature via WhatsApp and there is absolutely no response. I then logged a call with the support desk, but I was referred to the pathetic WhatsApp service and my ticket was closed.

I have no issues with the line itself. All I want is some direction in the management thereof but the customer service department is probably too busy reeling in new business so their existing customers are neglected. . This is really pathetic and now I see why so many people are leaving such bad reviews.
