Impossible to talk to the landlord of Park Clayton...

Impossible to talk to the landlord of Park Clayton Apts. We were asked few days ago to move out (3 of us, one baby and a cat) after 4 years that we have been living here, pack all our stuff and furniture, so they will put new pipes for a new washer and dryer. The worst thing is the manager didn't tell us for how long!!!
Very disappointed!
