The name on the contract with booking

Good evening this is urgent ,

I have received a contract from booking.com and there has been a mistake in some information.  According to the contract my name is Maria Repouliou and this is mentioned in the both fields "contact person" and "owner". I am not the owner of this property. I am currently the host and the owner's name is Γεώργιος Ρεπούλιος and she also should be a "contact person". His contact details are : +30 6932367796. Due to this mistake booking will not accept his tax number on the contract and we are  now very worried about having any problems with the tax office.

Please change this information in the new contract and resend it to this mail address. carpediem.corfu@yahoo.com

Thank you for your time.

Best regards,
