BAD CUSTOMER SERVICE

My 5G router has stopped working. I have phoned them on the 9th of Feb for assitance. Everytime I phoned they connected me to a tower and thats it. But the problem is not my network but the router that is faulty. On Friday 10 Feb I was advised that a dasher will phone me to come look at my router over the weekend. NO ONE PHONED ME. Here I am, almost 2 weeks without wifi, numerous phone calls to the call center and nothing. How many times must I phone for some assistance.
