Tdi Kundli — frequent power outage

Dear sir,
We are residing in j block since march 2019. Earlier there was no major issue regarding the basic amenities including water, electricity and so on, but a month later, we started facing a problem of a frequent power outage. We have raised this issue with the maintenance department multiple times but found no concrete solution. We are still not provided with any solution. Moreover, the concerned person in the maintenance dept. Is so rude that nobody could speak to him in person for the address of their grievances. He is such a pathetic person that i don't know how tdi has employed him for any sort of service. He is such an uncompetitive person that nobody could bother him for 15 seconds. Hereby i am requesting the tdi authority to either take immediate action on my grievances or i have to raise this issue to the higher authority. I can also resort on writing a letter to pmo if my issues are not addressed on time so please be fast in action.
