Waiting For The Agent to Call Back

I went to an open house in Robinson Grove, Bulleen a few weeks ago. The property was beautifully presented. It had 3 bedrooms, 1 bathroom and parking. The agent rang after a week to see whether I was interested in the property. I told the agent that I was not interested in the property as it was too small. The other reason I didn't like the property was because it had a block of flats behind.

Now, I have tried to contact this same agent four times regarding a price for a different property. The first was by email. The second time I rang the property Managers mobile but a message kept on saying that the mobile had "restricted incoming calls". I then rang the office but the secretary from Fletchers-Balwyn North said that she did not know the price of the home and that she had the same information I had. The office referred me to another agents mobile but I had to leave a message. I rang Saturday April 3rd and left a message. It is now April 7th and I still haven't anything.

All I want is a sale price. There is no price advertised on the internet. If I was the vendor I would be a little disappointed. I feel like knocking on the owners door myself, saying "I've tried to contact your agent for a price on your home four times but have been unsuccessful"

Update:
As I wasn't getting any response from the agent I decided to attended open house in Bulleen. Conflicting price ranges were given by same office. One sales person said $700,000-$770,000 and the other said $700,000-$800,000.

May 1st auction at Barak St, Bulleen.
As I mentioned price quoted at inspection was $700K-$800K. The auctioneer opened the auction at $700,000. While seling, the agent mentioned that the house had reached reserve at $ 820,000 and was on the market. The house sold for $945,000.
