Dear Mr. Sachin,

You can issue a legal notice to the purchaser stating all the facts of the case and further state that the money will not be refunded and legal consequences will follow with costs.

In case, you desire to go ahead with the transaction, you must show you readyness and willingness to perform your part of obligation under the Agreement and you can file a suit for specific performance as also damages against the purchaser.
