Can I use AOL computer repair to recover deleted files?

Hallo!
I am running Windows XP on my computer and I accidentally deleted some files the SHIFT DELETE way and so I do not have them resting in the Recycle Bin. I have read on the internet and found an AOL computer repair as a way that I could recover my deleted documents. Anyone who has ever signed up for AOL computer repair who can explain to me how effective this is before I can sign up? Thanks a lot.
