On and off all *** day...

Why am I paying for internet when it never works?? In fact, I have had to reconnect to my WIFI twice since starting this sentence. It's bullsh*t... I'm using a cox modem/router, did they give me a piece of **? I use my internet for my job, and when it doesn't work, neither do I. Not cool... WTF is going on??? I feeel like I should only be paying half my bill, since that's about the percentage my internet actually works!!
