Consumer Redressal

Dear Sir, I wolud like to inform you that I had booked the 200 sq gaz plots in Roza Jalalpur, Noida, Ghaziabad to a propert dealer in February, 2014. I gave him 600,000/- Rupees as a booking amount by bank transfer. At the time of booking he said that if the plots will not be according your choice, I will return your amount with in one month. After booking I found that the dealer is selling one plot to many people and he is sub agent not due to these reason I asked him to return my money he promised many times but could not return it. Now he is not receiving phone and replying my emails and smms. He gave me the one signed stamp paper to write that he has taken the 600000/- INR for the plot. Now I need my money, Please advise and help me what to do to recover my booking amount. I have his stamp paper agreement, email communications, whats app messages, typed broucher and bank transfer details. Looking forward to hearing from you soon to solve the problem.
