Realtor refused to present my offer on short sale. Is this legal?

[Rafael Davis]

I asked a realtor to present my offer to the seller on a short sale property he has listed, but he refused he said he won’t submit an offer for less than the asking price. The property has been listed for almost a year now I’m sure the bank is willing to negotiate if presented with an offer the property is in a nice area and will cash flow. What can I do to get my offer to the bank?
