Blizzard Entertainment review: fraud on my bank statement

on 10/20/2015 these charges of 59.98 were submitted to my bank statement, and as a result. i cannot get hold of them to ask what they are about, or if i can have the charges reversed. I know nothing about this company except that they are in California. phone number: [protected] I am a senior citizen, and don't go around do stupid things with my money. Please help if you can, get this reversed on my credit card.
