I purchased a flat from Starlite group (Website - starlite.in, Contact No - 033 4063 0402) in a residential complex "SUNNY BLISS" situated at 590 Anandapally, Purbapara,Kolkata- 700084.My property registration was completed on 12-Feb 2013 at Alipore Judges Civil Court in presence of Mr. Manoj Todi, on behalf of Starlite. Since I was outside India on business tour at the time of registration , my mother Mrs. Sikha Ray having power of attorney signed the deed on my behalf. Unfortunately she overlooked and signed the page having the wrong floor plan. The position of lift and staircase has been interchanged in the drawing, contrary to the actual scenario and consequently the area and design of my flat unit are affected. I called up the builder's office and requested to help me in getting this fixed, but they seemed reluctant to do this and refused to help me further. They are are ignoring my repeated phone calls and not ready to give a solution.I do not know how to get the recitification done in my deed without the cooperation of the developer. I have attached my wrong floor plan and the actual one.
