     Of course they can, if they have your mobile phone number [1]. You can   
   block them *after* the fact, delete their messages, etc., but you can   
   not prevent them from contacting you if they have your mobile phone   
   number.   
      
   [1] Actually your number for WhatsApp, not necessarily your (main)   
   mobile phone number, but let's not quarrel about that.
