Oracle Database Recover with prm-dul

I have a client that had a problem with an Oracle Database.

I try your product and recovered the 10000 records that the trial could recover, I’d already bought other products that I try and after bought they recover only 20%  records of the tables.

I have tables with more than 500000 records and the other products only recover 100000 I need to know if I can have more guaranties that I can recover more.

Can I send the data base to you and you send me one or two tables with all or almost all the records?

feedback :

yes, please send , and we will fix your problem
