Lower Monthly Bill

My wife and I are looking for someone to assist us in our efforts to lower our monthly bill.  Our total plan cost with fees and taxes went from $265 to $313 just this past month.  I contacted customer service today to see if there were any promotions that we could take advantage of but unfortunately there was not much that he could do.  The gentleman was very helpful and professional  but said there wasn’t much he was able to do.  We’ve been loyal Xfinity customers for over 8 years and subscribe to Home Security Pro, 210+channels, 1200mbps internet, and voice.  We enjoy our service but the costs have drastically increased over the course of the past month.  Any assistance would be greatly appreciated in helping us bring our price back down if possible.  Thank you.
