bill increase?

so I was paying 134.85. The price i locked into when i started the service.

It has now become 142.85 

A small jump, but not a (inset badword here) word on why/when it increased. And why as an internet provider do you not have a way to contact via online... only by phone (serriously, who wants to deal with your phone customer service) or through this forum so anyone can see my problem.
