On behalf of my father I am writing this email as the survey of my father's property has been completed since 04.03.20 and this is 2022 but still my father is waiting for the registery. He is a senior citizen 70+ but visited the processing center 4 times. He is helpless now can't visit the center anymore. Please tell us how long it would take to get registery. Dda people are sending us from one table to another and applying unnecessary Deficiency which we have already submitted but till now no response from dda staff through mail or in website.
