Who called from 9529999999

got a call from the #, but did not pick up cuz it was so strange

i got a call from this, but i won a contest for concert tickets, it seemed legit

I got a call from there too saying that I won tickets to a blink 182 concert. Legit?

i got a call and won a t-shirt and $400 it was legit too

I received a call from this # today and when I dialed the number back I kept getting a message saying the number is invalid. I enter a lot of contests too, so maybe it's valid and maybe it isn't! No message left to me from them.
