My mother lives in h.no. 798, second Floor, 3rd Phase, Cassia Omaxe, new Chandigarh.
She has undergone a knee operation. There is no lift in the flat and we have been requesting regularly in the past. I am trying to reach your electrical official here and he is not responding to my calls. It has been three years since there is no lift is being made accessible. Please take immediate measures kindly.
