I did not subscribe to any app and I did not buy anything and now Apple deducts my money 295.56 AED. I want to get back my money.

You are talking to other users, who have no access to your billing history.

If you see 'apple.com/bill' on your billing statement and cannot figure out what the charge is for, even after you've reviewed the charge online (as outlined in the Related Article), contact Apple Support (as also outlined there).

If you see 'apple.com/bill' on your billing statement - Apple Support

I see that although the LinkedIn app is free to download, it has In-App Purchases (subscriptions). Are you sure that you didn't sign up for one of them by mistake?

In any event, this is something you would need to take up with Apple and/or LinkedIn.
