Afrihost may have a backup of the machine that includes your data. Generally these backups are retained for around a week. If you ask nicely, then you can get a system administrator to restore your data from the backup. However, in this case you are out of luck, because it's been too long. The backups now are backing up the fact that the table does not have the data you are looking for.
