Service non-existent

I have been without wifi connectivity since 3/5/2022. Try calling their call center and I have to wait 45 minutes to speak to an agent. I was told that Vumatel did an upgrade without informing customers, how can they do that, what terrible customer service, absolutely disgusted by their service or lack of, actually. I work from home and have been unable to work as a result of not having wifi connectivity. Apparently I was supposed to receive a router within 2-3days but it hasn't even left their warehouse to the courier company as yet and this is day 4. Who is in charge here? Seems there is no management. I expect a refund for the days I have been without service.
