Horrible service

I would like to cancel my mom's subcription. She has been without internet connection for 10 days. I have escalated this issue more than 5 times already. First it was the tower,that was rrstpred bit the router never worked again. All the troubleshooting in the world has been done,possible router replacement mentioned but still nothing. we call Rain everday to yet another escalation opened. We have spent a lot of money on data as well. So please cancel!!!
