Even though Blizzard does not have a written refunds policy, it is possible to get your money back by contacting the customer support. Their support site has the option 'Refund game purchase' which you can use to get help. It is much easier to get a refund for new games than older ones.
Canceling Your Subscription
If you don't need a subscription anymore, you can cancel it in a few simple steps;
1. Log in to the page 'Games & Subscriptions
2. Lick on the option 'Manage' next to the account you would like to cancel
3. Click 'Cancel Subscription.' If you don't see the option, it means that you don't have an active subscription. It may have been canceled.
You can continue to play your game until the current game time expires. After that time, your account status will change to Inactive.

Getting a Refund from Blizzard
Refunds from Blizzard may take up to two weeks. However, thy typically take a few days. Blizzard tries to give you your refund as soon as possible.
The best way to get a refund is by contacting the support team as soon as possible. If you contact them a few hours after your purchase, your request will almost always be accepted.
Returning Your Digital Purchases
If the game you purchased is not working or has issues, you can request a refund. Contact Blizzard support and tell them the issue you are experiencing. Tell them that you are unable to use the game and would like a refund. If you contact them shortly after getting the game, they will take it away and give you your money back. You may purchase it later if you please.
Contacting the Support Team
The best way to contact Blizzard for your refund or any other form of support is on the help desk. Customer care agents are friendly and helpful. If you make your request for a refund soon after making your purchase, you are likely to get a refund. Note that it is not always possible. Be polite and respectful even when you feel frustrated. If one agent doesn't give you the help you need, you can call later. You may be connected with a different, more helpful one. Blizzard has plenty of phone numbers so you can always get help.
Blizzard's help desk has plenty of targeted tips and suggestions that may help you. It is the first place where most customers seek support before contacting the representatives directly. Go through the topics and pages to see if your issue is covered. Blizzard has an active help desk so it is easy to find help when you need it. When communicating with a customer care representative on the help desk, you may need to continue your conversation on email.
If your chat turns into an email conversation, the turnaround may be slower. It may take a few days before you get the help you need.
Email is another option to seek support if you don't need to speak with a representative. Keep your email brief but include details of all the issues you are experiencing.
Blizzard also offers support on Twitter. You will receive a response in a few hours. It is a great alternative if you don't mind waiting. They may call you or direct you to the relevant help on the help desk.
