Missed call.no message

I'm in the process of signing up with Direct TV. Called them yesterday(September 1st) get a call from these people today asking if I'm looking to get discounted internet or cable. I told them no and they hung up on me. not sure.

Got a call from them today as well. No message

I have gotten calls from this number and they are rude and hang up. No answer when called back.

i get a call from thud non-verbal once a day, no message ever left. managed to answer today and she identified herself as melissa from "discount cable company". i  told her i didn't have time for her nonsense, she begged my pardon so i asked what she needed. then she hung up.
