I bought a iPhone 5 they didn’t take activation lock, off of it. What do I do to take it off ?

Here's a guide from Apple Support on how to get Activation Lock removed:

Hello ~ That is the activation lock. If the person/persons that you bought the iPhone from cannot or will not remove it …the iPhone is basically useless to you. If they cannot/will not remove it…return it and get your money back. We cannot help remove it nor can Apple. Take a look here:

Ask the seller to remove the lock or give you a refund, or if applicable, ask the people running the store or website you bought it through for a refund. It's an anti-theft measure.
