This is a legit call from Comcast.  More exactly it's Xfinity Home.  They do have some pretty good deals.  I added Xfinity Home and my bill will be cheaper than what I am paying now.  I will be losing some TV channels I don't need or watch and it lowered my bill.

When I said hello all I heard was music playing. Then they hung up

This number calls once a day, usually during the evening.  Finally last night I answered and a male voice spoke in Spanish briefly and then in halting English said something like "Sorry wrong number. Sorry." and then hung up.  I thought that would be the last call, but tonight at around the same time, the call came again.  I cannot fathom that it was actually Comcast.  They could (and have here) easily change their caller name, considering that they've had this Xfinity name for quite a long time - and it includes phone services.  Someone may be spoofing this number. Just saying, for it happens more and more often these days.

ID said Comcast. I answered and after some music and clicks a woman comes speaking very broken English like Indian and asked for me. With the accent I hung up, not believing Comcast would have people calling me not speaking English.

could barely understand female caller.  Very heavy Indian accent.  Is this for real????  Very weird attempt to sell me what???  i hung up.  I have gotten several phishing emails that said Comcast and were not, is this the phone version?????
