Builder money fraud cheating with money of rupees 15lakhs

Respected Sir I would like to seek your kind assistance on builder money fraud based in Chennai, for cheating me with money. I had entered into a contract with builder to purchase a new apartment for me at Chennai as per the agreement provided by the builder to pay a total amount of Rupees 72,25,000 in installments to get that apartment. I have made a total sum of (Fifteen Lakhs Rupees) payment of Rupees 15,00,000 in cash from the year December 2017 to November 2020. I have made all the payments through cheques for which I have proof. He kept demanding money at short intervals making false promises that the plan would soon arrive and he would start the construction soon then. But the construction plan hadn’t arrived even till 2018. Finally, in 2019 he informed us that the plan had arrived and assured us he would complete the project shortly. I visited India in December 2020 during COVID-19 he demanded to pay him amount of 25 lakhs rupees, and the apartment was not constructed. In the last call, he was abusing us for not paying the amount and suddenly disappeared. Furthermore, I have repeatedly attempted to call him since 2021 but he never answered my phone calls. However, builder had failed to complete the construction on time. Instead, he used to call and trouble my mother who was a senior citizen. Now and then my mother kept telling me that builder shouted over the phone demanding money. Many times she complained of chest pain as she was under stress and trauma due to his persistent harassment. He started taking advantage of my parents’ growing old age and gave them mental trauma. My mother passed away in November 2020 due to cardiac arrest just 2 days before her demise she told me over the phone that she had developed a fear of builder phone calls as he was giving them mental torture for money. Firstly, he delayed the construction from the year December 2017 to August 2019. During this tenure, I repeatedly approached builder, but he refused to give us a clear update regarding the status of the construction. My Father has been a heart patient since my mother's sudden demise he is on anti-depressants now and lives with his children abroad. Whenever I attempt to approach him he demands my father’s involvement as he knows my father is weak and physically unstable to deal with the issue. The agreement is in my name and he has always dealt with my husband and me. He wants to divert the case so he simply wants to find excuses to manage his fraudulent activities as he had managed with others in the past. I approached many people who had purchased flats from him they have the same agreement as I have. Some have already sold out the purchased apartment and some are struggling to sell them. As his construction is of third-class quality and there is no proper documentation. From one of my relatives, I discovered that builder had let out my flat for rent or sold out to someone. I frequently made attempts to get in touch with him, but there was no response from his side neither on-call nor message. I traveled to Chennai - India in March 2024 and filed a complaint against him in various portals such as CM cell, NRI cell, and Human Rights Commission but every time I visit Chennai he doesn't show up. He gives false excuses saying either he is on pilgrimage or a business visit. I visited Police Station several times but sadly every time I had to face disappointment as there was no action taken by them. Police officials either delayed an inquiry against him or kept my complaint on hold and didn't even register my case. When I was visiting the official premises and started dealing legally with him I was continuously receiving threatening phone calls. I was told that he is highly influential and has a lot of political support. I was asked to withdraw the complaints against him. I am a lady with special needs. I believe that builder has cheated me with money and also I heard from my elder sister that he was not willing to talk to her and refund her money, and for that, she too has filed a complaint against him. I would like to inform you that he has breached the terms of our contract. Thank you for your time and attention to this matter. Sincerely Ms. Wahida Farzana
