There is a small sitting/play area under both of my bedrooms windows . I've asked management to enforce the rule of locking the park at 9pm, using a different lock than all shareholders have to gain access to the park (otherwise any tenant can enter at any hour)I have made this request twice, last time in writing; still no reply. Warm weather is coming; the super lives on premises. What can I do to at least get a reply and at most get them to act on my request so that i can enjoy my bedroom after 9pm?
