I took advantage of an Xfinity promo that upgraded my service to 200 Mbs and 10 tv channels. I've decided I don't want this service anymore and would like to revert back to my old $30 a month plan. However, there seems to be no way for me to do so on my own. It only shows me offers that includes TV, which I do not need. Is there a way to revert back to my old plan as I cannot stomach the new bill.
