Refurbished router

Very bad, we lost connection of the fiber on Thursday the 9th Nov around 20h00, Friday morning I logged a call, the Vuma cable was sorted very quick with no hassle at all, I then called Afrihost to inform them that the cable is fixed but still not able to connect to the router, I was then instructed to restarted it, which we did,after restarting we are still not able to connect, now we can tell then that we can't pick up out router but another router, we have since established that when our original router broke 4 months ago, it was replaced with a refurbished router not a new one, since Thursday night we don't have connection, we now have to buy data as the kids are studying for final exams and they have to prepare, this is the highest incompetence I have ever experienced, I have been with Afrihost for over 8 years, but what is currently happening I am very disappointed, the call center agents don't have an idea of what they are doing
