How to not receive phone messages from Gameflip

I have just received text message from you guys saying “Welcome to Gameflip, we’ve added $1 in Credits for your first purchase. Hurry, expires in 2 days.”

I don’t wanna receive any more messages from Gameflip, is there anyway to block it?

Hey, we may need to supend your account for this not to happen anymore.
