Delhi Development Authority [DDA] — i am complaining about unmaintained swimming pool and unhygienic pool conditions

Address: 110093

Sir,
I have complain regarding swimming pool running under dda as franchise in kaant nagar, east delhi.
My membership number is 363/d and i have membership for 6 months
From past 20 days, water in the pool is quite dirty and can't be used for swimming, despite of repeated reminders to authority and their repeated assurance, they have failed to provide clean pool.
Now, after several complains the manager refuses to meet us and keep us telling that other day pool will be all right, but to no avail. I visit pool after their assurance but condition is never better.
I request you to take it as a serious matter as it is causing harm to my money, time and your name.
Thankyou
