No Internet For 24 Hours And Counting

Vumatel engineer came out to help the upstairs apartment with installation, said there was an issue with the fibre line and they "needed to fetch replacement cable". It's now been 24 hours where the entire property has no internet. My ISP says "Vumatel will be in contact to make an appointment". I work online and am losing money with each hour that Vuma doesn't fix whatever they broke.
