His right, its account hijackeing problem then scamming problem. You should make ticket on steam support.
Please submit a ticket to Steam support & then post a screenshot of it here (with private information removed, of course). If the person is logging into your account and trading items without your authorization, you need to report this to Valve as well as make sure you change/secure all your account information. Let me know if you need any help.
