Horrible Service

Unable to use my WiFi for the past 3 days , tried to get to their customer service line. Spoke to an agent who is unable to answer any of my questions. Their tech team came & checked the WiFi & said it should be resolved the next day it’s been 5 days now & I still don’t have access to the WiFi that I paid for. I keep on receiving messages that it will expire , how when it was not even used ?????
