Called me in my cell claiming I have a warrant for my arrest, & claiming they can help me set up payment & deter my arrest, & make payment arrangements & finally that I need to turn myself in, when asked where & who to turn myself in to. They hung up on me.

If they continue to call me what actions can I take? Is this a legit business, & I've never known about anyone calling individuals about warrants.
Their contact number is 1.512.582.8040.

Thank you
