Offer accepted, Bank of NY-Mellon send back completley different

[John Ewas]

Made best offer on a H&B house. I won, broker accepted my offer. I just got the P&S back, closing date it longer, no inspection, and they want me to pay them the $$$ tomorrow rather than this friday. Seems pretty harsh. They are trying to bully me.

 The big question is, if they accepted my offer, do they have to abide by the terms ? Broker said if I don't pay up tomorrow, they will throw me out and sell to the next highest bidder. Anyone ever sued a Bank and won for breach of contract ? 

thanks
