Divya Delhi: DDA Extends Dwarka 19B Premium Flat Payment Deadline to September 30.Delhi Development Authority flat buyers are relieved. DDA has extended the last instalment deadline for over 1,800 premium units in Dwarka 19B. Flats were sold by e-auction. September 30, instead of August 31, is the new deadline for paying 25% of the entire fee. The buyers requested this decision, according to the authority. They needed additional time to secure funds. Due to remaining work, the deadline was extended. Home buyers have also claimed that DDA has not yet installed electricity and water, built major gates, hired security guards, and developed entertainment parks. Slow work frustrates homebuyers: A DDA flat buyer claims he paid 100%. We bought a 3-BHK e-auction flat and considered moving during Dussehra or Diwali. The flat lacks electricity and water.
