Q: Can i get a refund on my previous purchase? It is because that the purchase is wrongly click by my relative.

In your emailed receipt from Apple there should be a place to contact the store and ask about this.  In my own receipts from the iTunes store there is a link called "report a problem".

When in my photos a message came up to add storage because there was not enough room.  I did not know you were charging me for .99 and 2.00, please refund my funds as soon as possible as I did not order this.

HHow do I get refund if I didn't order netflix

Why do you think that you've been charged for Netflix ? There are a number of phishing emails doing the rounds claiming that Netflix has been subscribed to, if you've received an email :

Phishing and similar emails : Phishing & Other Suspicious Emails

Phishing emails : Identifying fraudulent "phishing" email - Apple Support

Genuine iTunes emails : Identifying legitimate emails from the iTunes Store - Apple Support

Viewing your account's purchase history : See your purchase history in the iTunes Store - Apple Support (on an iOS device you can view the last 90 days purchases via http://reportaproblem.apple.com)

If it's a genuine email and it shows on your account's purchase history, and nobody else has access to your account or devices/computers, then contact iTunes Support : http://www.apple.com/support/itunes/contact/  . And change your account's password http://appleid.apple.com - after changing it : What to do after you change your Apple ID email address or password - Apple Support.

If it is a phishing email you could forward it to Apple : reportphishing@apple.com , and then delete it.

If it's a phishing attempt and you clicked on the link in the email and entered your account id and password then change your password immediately

These are user-to-user forums, nobody on here can refund you.

Try contacting iTunes Support and see if they will refund you (purchases are considered final) : http://reportaproblem.apple.com or https://www.apple.com/emea/support/itunes/contact.html
