Ghaziabad Nagar Nigam — Young people not allowed to play in the park

Resident of Patel Nagar II, D Block colony, we are not allowed to play in the park by a handful people who charge a maintenance per month but have restricted us from playing in the park, a game like badminton doesn't harm any leaves or flower but they don't let us play .
Park is a public property and everyone should be allowed to play games provided it doesn't cause any problem . Those people have put a notice outside park refraining people from Playing .
As per them the growth of grass gets hampered in the area where a person stands but then a person stands for hardly an hour and after all a park is not a tourist spot neither its a museum that people simply stare at the park . Also we are not playing cricket or football so those people should not stop us from playing in the park .
In addition to that there is another park just adjacent to this park and there is no restriction there, kids in that park even play cricket but no one stops them so why in our colony a handful people are creating this mess, in the name of maintenance only grass is leveled on monthly basis, rest there is no such thing so on what grounds can they simply refrain us from playing .

It is an earnest request from my side to take action at the earliest as we like playing as it refreshes our mind and keeps us healthy, Hope that the notice outside park will be removed and we would be allowed to play again .
