Delhi Development Authority [DDA] — no online payment method despite of demonetisation

Address:

New Delhi, Delhi, 110064

I have been going to the dda sports complex in hari nagar almost everyday for the past month. First of all i would like to say that it is well maintained and the swimming pool is clean as well.
But there is a lot of inconvenience as i have to carry cash everyday that too the exact change as they don't have change most of the time.
It has been more than 9 months since the demonetisation, then why has there not been a online payment method set at facilities like dda sports complexes, since they come directly under the government's authority.
Also, if anyone wants to apply for a membership they have to make the payment through a demand draft. Why have you not introduced payment methods like debit/credit cards, e-wallets etc.
It is extremely disappointing that the citizens of the country have to make adjustments and suffer in the case of demonetisation but the government is not willing to act or take initiatives.
