They dont know what customer means, they feel they can ride on the customers by slowing down the work and not allowing to do any changes to the plan and constructing extra floors. Sending some workers to create nuisance in apartment compounds etc. For any pending work they will tell tomorrow we will do for sure, you call them every day they will repeat the same thing.
If you feel like buying any flat is better to go for a completed project than under construction apartment from this builder.
