I have purchased on Office 365 Personal last year on 16th September 2015 for One year only.

But today I saw ₹ 3299 has been debited in my same credit card which was used to purchase the above said office 365 Personal one year back.

This year I don't require to renew the same due to not used of office anymore.

how can you charge without any confirmation from my side, also if charged they didn't send any invoice for the same.

I didn't receive any reminder for renewal or charging on my credit card.

Request you to please return my money immediately.
