Hi Oliveiros,
With your query I get the following result
date | theme | receiver | count
------------------------------------+----------+----------------------+-------
2007-04-27 00:00:00+00 | MIA | +40741775621 | 25
2007-04-25 00:00:00+00 | LIA | +40741775621 | 50
2007-05-09 00:00:00+00 | MIA | +40741775621 | 1
2007-04-27 00:00:00+00 | LIA | +40741775621 | 81
The count it is not correct.
Best,
