S.V.N. Abhigyan Constructions Pvt. Ltd. - Poor construction of my house

I am a private employee of the company (Abhigyan construction Pvt. Ltd/builder) has not provided quality construction to my house, plot no. ** in heaven’s corner project, Manneguda, Turkayamjal, ranga reddy district. I have purchased “design-build” contractor services for my house on *th June ****. I have suffered a lot of mental, financial and time delay difficulties with the builder as he has not performed the construction to a minimum standard. I have attached one of the evidence as proof for his poor construction work for main entrance door frames, which I can see the gap between the wall and door frame. I have addressed many times with several photographs and email correspondences to the builder, but he is least bothered about his clients/customers.
Please kindly enforce the builder to complete the works for plot ** with the highest priority as it was already delayed with best quality finishing. I can share more evidence and photographs for further process.
Thank you for accepting my complaint.
