JohnG per Xfinity suggestions madwe changes that now cost me double

I spoke with a John about 3 weeks ago He was wonderful....helps with correcting issue with new phones HOWEVER I need to speak to a manager.  Taking Xfinitie's suggestions and goinv from a landline to a wireless instead would save money.  Trade in old phones for a modeal that was to be filly on xfinity.  Now My mobile bill is 3 times what it was and my "landline" internet and cable is almost $200.00.  So your "save money suggestions" have almost doubled what I was paying.  I would like a manager to call me regarding this as everytime I call or chat...everything is "rectified" and you are very soryy...but NO...I actually kept all transcripts stating the above...unfortuantely NOTHING is easy dealing with you, actually it is horrible
