Stay away from this company

I paid cash for my router in 2019. Apparently, they were not supposed to accept cash. Now, over 4 years later, they are asking me to return the router. It is mine. I own it. Also, as in so many other reviews of this company, there were billing issues which - I was told - were sorted out. No, they never sorted out anything. These people are ****s and *****sters; and good luck trying to contact them.
