Who called from 5052739221

Just got a call from this number. She said it was a sweepstake thing regarding gift certificates. Would not stop giving me the pitch. I told her this is a cellphone and to take me off their call list. She was still talking over me and I hung up.

They keep on calling when I answer they listen and then hang up

Got a call today 1/21/16 at 3:15 pm. Ask me to do a survey and could win a gift card. I hung up and blocked the number. They were recording the call.
