Poor service with non working 5G router

I have bought my 5G router on the 7th of this month it hasn't worked until to-date I have been collecting their support online group, instead I'm promised call backs, the last time I called was on the 18th in which I was promised a callback from technicians as my router needs a technician because apparently it doesn't show on their system so a technician needs to do a home visit ,in which I was a call before the end of business day byThato I'm still waiting for their call and the technician it's going for a month now me wasting my money calling.
