Hi I'm Fabio I'll support you today.
If I have understood correctly you need to update or add your new address and contact details to the map database.
You can suggest new business details through the dedicated form that you find here https://support.google.com/maps/answer/6320846?hl=en
You find the instructions in that page but if you need further help feel free to come back to me.
Did you have the chance to try my solution?
