How can I purge "Trash Entries" ?

I have deleted all my entries however , it still stays I have low space and before deleting the data it was showing 63.0... mb was consumed..

I did follow the instructions and deleted all the items in trash but still I have the same issue

Hi, 

I checked your problem and I can see you deleted some submissions but those have been moved to "TRASHED ENTRIES". Your deleted submission stays in trashed entries for 30 days and then will delete permanently. Forms in the trash and archive folders still take up space if it has submissions that have associated file uploads.

You can follow the below steps for purge "TRASH ENTRIES";

1. Go to your My Forms page.
2. Select the form with the submissions you want to delete.
3. Click the Submissions button at the top of the page 
4. Click the three vertical dots icon on the main submissions tab.
5. Click the Trashed entries option.
6. In the trash section, check the Select All option.
7. Click the Delete Forever button, and confirm the deletion in the popup window. Then you’re done.

I have done the same , but I still have the same storage issue. Please advice
