No wifi

My WiFi hasn’t been working for the past week communicated with Fibler since I have a contract with them and they said they will come sort out my issue. But still today no WiFi no communication from Vuma and left with no WiFi. Tried calling their customer care but to no avail. I’m so angry and frustrated cause I can’t do anything in my house without WiFi . I can’t be paying for something and not getting any service and help
