I think someone is using my account

So I've not seen any purchases or anything but recently whenever I use 2-step verification I receive the verification code either not at all or with a delay coming from a normal phone number from a different country. I've changed passwords and verified my phonenumber but it still seems this way. Also sometimes I get notifications from games that my local storage doesnt allign because my online storage is different from another console.. when I only game on mine...
