I have a issue with a real estate agent

If you have bought a property that is different and smaller than what you have agreed with the landlord, then you have the right to raise a claim and file a case at court, and that is in order to terminate the contract and take back your money. Otherwise, he / she is obligated to deliver to you the property that was agreed upon. The contract is the main tool between the two parties, and if there is any breach to that contract, then you have the right to terminate it.
