I have contacted customer service on 5 different occasions for assistance with returning the 5G router and extender after cancelling my account. Each time they tell me I will receive a return kit within 5 days. I have never received anything from them except empty promises. I cancelled the account because they promised a $200 Target gift certificate along with a Nintendo Switch for switching to their 5G Internet service. I did not receive either even after 14 hours of calls with customer service. I notice many others are having the same problems. This is terrible service!
