Poor Park maintenance

Hi I have logged two queries for park maintenance in our area (Brackenfell), but each time it is closed by the inspector.

The park at the back of my house has been cut, but all the ******* has just been left? There is a huge tree that needs trimming, but this is also not done. The cars cant even park there any longer as the tree branches is reaching to almost the ground? Furthermore the sidewalk under the tree is so overgrown with ****/grass that each time it rains, the rainwater drains is blocked and we have a whole dam for a week or two? Even the ducks move in so deep is the water? The “river” is also overgrown with reeds and as a result we have lots of mosquitos! Im not sure where to go to at this stage and hope this platform can assist!
