Try Recuva: https://www.piriform.com/recuva
I believe it has a demo/preview mode in which it tells you what it could recover if you paid them.
If it shows you your files, pay them 25 bucks and recover your data. If not, pay the other guy 90 bucks.
If you do not know how to run Recuva, pay the other guy the 90 bucks :-)
