Poor service from Vumatel

We pay for a service through our service provider, Vox but when there is a problem, no-one takes the client seriously. I reported an interruption in our Wi-Fi this afternoon - my first call to Vox was about lunch time. I called them a couple of times and they then logged a call (ticket) with Vumatel late this afternoon. Vumatel now tells me that I must wait for someone to check my lines tomorrow!! My daughter works from home and is in meetings all day. Why must we be inconvenienced because they cannot plan for these situations? Absolutely ridiculous!
