A DNG agent in my area did not return calls or e-mails after I placed a cash offer in person at his office on a property he was representing, that was months back, very frustrating and as it happens the property is still listed for sale so yes, par for the course I'm afraid but really hard to believe, I often wonder if the sellers were aware or interested even in the sloppiness and unprofessional behaviours displayed by some of the agents out there hired to represent their interests.
