Municipal Corporation Of Delhi — maintenance of ground

I had raised a complaint in the past that park opposite gk2 's block is not properly maintained at all however no action was taken... Toilets are very dirty and leaking from the roof... Unwanted garbage is lieying around the tennis court... Court itself is pretty badly maintained as no red mud is provided for the past many years for its maintenance. Courts are open to all and no fee is been charged but kids have in the past got hurt by playing on the rough surface. Rwa has taken no action.. Humble request to please resolve this.
