Website:	Google Play

Google Play deducted rs. 300/- on 18/4/17 and rs. 130/- on 20/4/17 from my account without any authority, I never used my debit card to make any purchase in Google Play. This is a very serious issue, how can google deduct money from me without my authorization and that too twice. It's a serious threat to someone's privacy. Kindly look into the matter because it's a serious issue
