Lousy Customer service

Over a week ago I moved ,hooked my cable box up and no TV. contacted XFINITY tried to work though issues to no avail after 40 minutes on the phone,scheduled a technician to trouble shoot cable box issues a WEEK later!!!!!! quess who never showed up to the scheduled appointment ,The tech ,even after at least 4 text updates be there soon !!!  NO SHOW ALL DAY !!!! Called XFINITY back to get only lip service and reschedule appointment for two more days without cable service. "Nel" the customer service agent had nothing but lip service said it was 3 O'clock PM and was to late to have a tech show up now but could get someone out in two days,"Nel" was unwilling to provide any email address to anyone who cared about CUSTOMER SERVICE hopefully someone out there can provide me with someone who cares !!!!!! or at least give something other than apologies and lipm service
