My plan changed and increased without my authorization!

Yesterday afternoon (Dec 22nd, 5:19 pm EST) I received an Xfinity email that my plan's cost increased from $63/month to $103/month!  I contacted Xfinity billing after and a representative told me that I had changed my plan.  I have NO record of changing my plan.  The only conversation I have had with Xfinity was yesterday morning talking with technical support about another email I received about a 'planned outage' ('Enhancing the Xfinity network.., Dec 22nd, 6:44 am EST).  There was no plan changes made and again I have no record of any change.  And before this call I have not contacted Xfinity since Dec 17th, and this was also about a lengthy outage in progress.   So I'm not. sure why Xfinity changed my plan.  
I was on the call with your representatives for a couple of hours late yesterday afternoon, going around in circles on this.  Finally the representative gave me a discount, knocked the price down for $60/month.  But he said the new plan was for a year but I don't see anything on the plan that indicates the term.  Can a Xfinity representative please check the term period and verify what my plan is?  He also put me on a 1Gig plan but I don't need this.  

After going through all this I am losing trust in Xfinity.  I recently move my mobile plan over but now I am regretting this decision and if things don't improve soon will be shopping elsewhere for both mobile and internet providers.
Thanks!
