I keep getting text messages from this number: 760-822-3095 like 'Hi', 'Wake up'.  There are some missed calls also from number.  I tried calling this number several times and no one answers.  After repeated attempts somebody answers and says 'they have not done anything and tell your provider to block my number'.  My provider - Sprint says 'they can not block a single number and if you want you can cancel text messaging'.
