Terrible service from Metrofibre

Hi, I recently joined metro fibre in October. I moved to a new address in November and I paid for November & December. I was told to unplug my router and take it with to my new place and they will connect it. Till today my Internet is still not running & every time I contact them they have a different excuse as to why it's not set up yet. I don't see why I have to pay for a service I'm not receiving. I've wasted so much money on airtime just phoning them yet the issue hasn't been resolved. I'm at a point where I want to drop my router at their office and demand my money back only to find out their offices are closed until Jan which means I'll most likely have to wait till end of Jan to get my Internet running. I'm very disappointed in their service they're very unprofessional and I don't recommend anyone use them because in this day and age it's very difficult to go without Internet and they show no sense of urgency to resolve this matter.
