Evotel I am so disappointed

So disappointed evotel rooted is faulty and I am told that there is a turnaround of 72hours for a technician to come out to bring a other router. It has just been month end and statement ect must be send out but cant without the internet. I even offered to fetch a router and have one of our employees put it in but the call centre says it can't be done I regret going to Fibre as I never had this before with just a normal line.
