After listing expired, agent complained listing price too high and won't return house keys. Asking for keys back finally she mailed in regular envelope but nothing in it when I got the mail. So far I still don't get my house lock fixed. One said she got one key only but the other said that she got two keys for the same door lock. I just wonder how can agent get in house to have a showing with two doors locked. More than one and half months still don't take care of their mistake.
