This is a perfect example of why you should be working with your own buyers agent. Agents/brokers are duty bound to present all offers in a timely fashion, when they are working as your contracted agent. You didn't mention in what capacity you engaged this agent/broker. Here in Massachusetts they are required to disclose their capacity as either a sellers agent, buyers agent, dual agent or designated agent. Each of these types of agency relationship has different rules and guidelines and levels of service to you and the seller. I agree with Shanna, proving exactly what happened conclusively would be difficult but at the end of the day unless you contract with your own buyers agent your rights and protections would not be as protected. You should never feel this way when you're working with a real estate professional. Without clarification of the status of the agents agency relationship this type of situation could easily happen again. You should consult the Mandatory Relationship Disclosure form that you should be provided to see these differences and if you're unclear of the meanings consult with your own real estate attorney for legal clarification. When a buyer works with the listing agent using your own attorney is vital to protect your interests. The sellers agent/listing agent may be following guidelines from their client that they may not have to disclose to you. This is why you need your own representation. Hope this helps, let us know how you make out.
