Varify there patients contact addresses

This is a complaint to the accounts department regarding an account that is sent to my address and i Have on numerous times sent emails and telephonic calls regarding this. The account is for a person namely A. Hoffmann who is using my address 93 Milnerton Drive, Milnerton Ridge. This morning called again five times not able to get hold of anybody. I have received a final demand on this account. Have returned the mail back but with our mail post who knows if it gets returned??? Hopefully this can be sorted out once and for all putting it up on Hello Peter.
