24 hours and still no network

I have been using Metrofiber go for 3 months now with out a problem, but yesterday I had my first issue and I called them to see if they can assist but the lady on the phone just said switch the device off for 10 minutes then it will be ok. I did that and still it was not working, then I sent a WhatsApp message where I even sent a screenshot of the router and they responded saying an agent will contact me. But no one contacted me and I’m still of line . The problem is I had to buy airtime and data because I use data for almost everything in my home.
