Metrofibre poor service delivery

I have paid an activation fee of R260 with Metrofibre on the 12th of February 2022. The guys where quick to come and install the fiber line to the house by Wednesday and by the next day the technician installed the router. Ever since the installation I’ve been struggling to connect to the internet, I’ve been calling this guys every since the 17th of February 2022 and I still can’t connect to the internet today 26 February 2022. When I checked with them the serial number of the router that was installed it was registered in the wrong name. They then logged a ticket for the router to be changed and the technician just changed the router and left saying that it’s not happening responsibility to check if everything on the router is fine and if it’s working perfectly and connecting to the internet. The router is working fine but even after changing the router I still can’t connect to the internet. I was suppose to get 2 weeks of free excess to the internet but I’ve never even enjoyed the benefits of the fiber. I’ve even tried to recharge with a voucher twice to see if it will connect to the internet but no response, nothing. It’s been days calling Metrofibre to resolve the issue so I can get access to the internet but I’m still struggling with internet connection and no one is coming to resolve the issue. They keep trying me that on the system it shows that my account is active and running but I’m still not connecting to the internet and they fail to just let a technician come and have a look at what might be the problem of me not connecting to this internet. I’m very disappointed in Metrofibre for this kinda service, calling everyday and I’m not getting a solution even today.
