Poor customer service

Ever since my router was installed it only worked on the day it was installed which was on the 28 August till today I don’t have internet access, they keep on logging million calls and escalating,is like they are hearing this two words for the first time. I wish they can come and collect this piece of junk because it does not even fit to be part of my decoration. They waiting for metro fibre to come and fix the connection for the past three weeks.
