I Have a Question

I checked my emails and I keep getting strange emails from apple basically like confirm of receipt emails but things i have not ordered like a navigation system. And Netflix subscription 1 month and I paid it with my iTunes account i don't have an iTunes account and my sister pays Netflix so why do you think i keep getting these emails or do you think it is some kind of scam apparently I ordered it on 7th June last month but I didn't and it cost 32.99 tried to look into it but asks for personal information like name address and bank details do you think it is a scam.
