Horrible service provider

We have been struggling since last week with our WiFi router. We called on Saturday and they advised us that it should be fine by Monday, we called again today and have been put on hold for 15min and they just said we should reboot the router but still nothing. This network provider doesn’t care about customers and it’s really frustrating considering the fact that the little ones are home and can’t use the WiFi meaning we constantly have to keep buying data! I am absolutely disappointed and would never recommend it to anyone. We are paying for a service that doesn’t work
