Terrible service, no urgency what so ever

Our rooter stop working suddenly yesterday (08/12/2022), it does not switch on. We contacted the service provider and they advise they can only send someone to have a look at it in 3-4 working days. Now, my husband and I both work from home and constantly need to have our WIFI operating. We can't work as is, we made another call this morning and again we were promised someone would call us back in 24-48 hours and that someone will be sent to check it in 3-4 working days. It is such poor service that the service provider cannot send someone urgently to assist us. We don't have 3-4 working days not to work, it is such an inconvenience and such bad service. We are told we have to be patient. Our account is up to date and we are told we have to wait. This is disappointing from Rain, we could switch providers and get another rooter today while they tell us to wait, but we have to work.
