Comcast Xfinity Lied to about Free Installation! Getting the runaround to be credited! Nationwide

This is the condensed version as it would take hours to write all details.  it has now been 4 months since I moved and was told I would have free installation, this after finally calling Comcast to cancel!!   I was sooooo excited to finally be done with the worst customer service in the world!  No more rude CSR's who can barely speak English, no more ridiculously high cable/internet bills.. Done!  Or so I thought.....  I totally fell for the lies about free installation and a "great monthly rate and to top it off, free land line she was "throwing in for fneed to say to keep customers from canceling.   so of course..  the first bill had the installation charge not to mention an addit I was told after numerous and I do mean numerous calls that I would be credited even though they could see no notes of me being told that I would get a free installation and it's not something they normally do.  I said well why ïdon't they just listen to the "recording"? That would resolve everything!  They said they gave to put in a ticket.. Ok well do it! 

When I called Wednesday December 24th because my service was disconnected!  (oh yes, in the muddle of this dispute they had the audacity to disconnect my service and I had to pay $300! To get my service restored) I  was told they now see a "note" from the 14th that a credit is being issued but they couldn't tell me for how much or what the credit was for exactly?  What???

I have followed other exhausted, infuriated customers and have written a letter to Tom Karinshak, Senior Vice President of Customer Experience at Comcast - Who encourages customers with issues to write so do it! - you can find his email address at the bottom of the "contact us" page on Comcast.com -   If he really does exist, he must be an extremely busy guy just reading complaint letters alone! Absolutely ridiculous. I am kicking myself for staying with this horrible company! But I will not give up like they want me to. It's just not right to tell people things just to keep a customer and then not stand by your word! Way to do business Comcast... You should be ashamed! Maybe Tom will do something to turn the worst customer service departments in business today around? I won't hold my breath!  But I will keep pursuing my refund on every web site I can find!  Trust and believe that Comcast!!
