How to get refund of advance money from property seller

 I was purchasing a property for consideration of 7.50 lacs. So i have paid advance money of Rs.55k through cheque. But later on various issues come with property so i declined to seller to purchase property and demanded my advance money to refund due to following reasons: 1. There is passing high tension wire over the roof of property at the height of 7-8 feet. At the time of showing property the seller had said that there is no current in the wire and someone can catch the wire with hand but taking advance money he is now saying to stay carefully. 2. The property is on genreal power of attorney through multiple chain and further the person to whom name property is registered can not identified. 3. As per supreme court order no one can purchase or sell property through power of attorney. can it be ground for getting my advance money back .What legal action can I take?
