We are getting mail returned that has the correct address on it. It says could not forward do to insufficient information on address. Everything is legible and address is complete with ZIP code. The address is 4494 Harmony Point Lane Boulder Junction WI. 54512 We have been sending mail there for years to parents and there is no change of address. Can you tell why this is happening? Again it is a long time address of parents and there have not been any changes. We check address everytime and it is correct and very legible. My phone number is 812-655-5055 in case you need it.
