A week or two ago someone used my psn account to make a new child account. I caught it because my email was saying I was making a bunch of purchases. I checked my credit card and there were no charges on it. So I changed their password because I was the family manager. Then I changed mine, added two step varification and everything has been fine since. When I first logged into destiny after the account. It said I have -4500 silver. I don't get why because I've had no charges to my credit card and even if the person who added themselves to my psn, family account downloaded Destiny 2 and bought silver, I didn't pay for it and it wasn't on my psn account. I buy silver every once in a while and would like to during the festival of the lost. Please help me to understand what happened and how it can be fixed. Thank you.
