comcast xfinity promotional fraud philadelphia Pennsylvania

 i ordered    comcast  xfinity online in  oct  2016.       the package deal   came with a $100      reward  card after 90  days.    its been  120  days,no reward card.    contacted  comcast twice today   .     first time i was told i was wrong    the package i ordered  did not have a reward card.      they  claimed to pull up  my order  onlinre but refused to send me a  copy of   it.  then told me  they would investigate it .      got an email   3 hours later,  guess what? you get nothing.        went back online again   at  3:30  pm   .     was told  they  can't  look  online,   contradicting what i was told this morning.   said it would take  24-72 hours  to investigate this,   really?   i  consider this fraud  and decptive    practices. it  becomes   my word against theirs. they  don't seem to care    about the  customers.     looking thru   online chat forums. it seems lots of people have this same issue or similar.  comcast   refuses to  honor  its   promotional deals.      this  is a breach of contract   to me.
