I dont have an Iphone, but my address, on Iphone maps is wrong, how does it get updated

Bring up your business on the map and on the left side of the screen, there should be a popup describing the business. Scroll to the bottom of the popup and tap Report an Issue. Select Location on Map. Set the correct location, then tap Send at the top.

Can you borrow a phone or ask a customer to do the above? If you can access a Mac computer, open the Maps application, and under the Maps menu at the top, select Report an Issue.
