Space Not Raclaimed After Reorg

 After table Reorg by the below method Space is not reclaimed.

For Partitioned Tables

1. Move the Table partitions

ALTER TABLE  <TABLE_NAME>  MOVE PARTITION  <PARTITION_NAME>  TABLESPACE XYZ ;

2. Rebuild Index

ALTER INDEX <INDEX_NAME>  REBUILD ONLINE;

3. Gather Stats

exec dbms_stats.gather_table_stats(ownname=>'SCHEMA_NAME',tabname=>'TABLE_NAME',estimate_percent => dbms_stats.auto_sample_size,degree=7,granularity=>'GLOBAL AND 

PARTITION',cascade=>true);

Can anyone suggest.
