why am getting these texts?

Hi Team

Why am I getting all this advertisement

the other day I got a text from countdown and I don't even have a onecard

when I looked up the shortcode 5282 it comes up as ''Burst SMS - Hyundai''

now it's about hair.. I recently went to rodney wayne for a

hair color and they wanted my contact phone number it looks like they have passed on my number to a third party for the purpose of advertising.
