Is it unreasonable to ask for maintenance bills from landlords?

I have been living in a rented apartment since 2020. The apartment complex consists of 20 units, and all the owners are from the same family. We pay ₹2500 as maintenance to the owners' welfare association but have never received any bills. Several issues have occurred, like parcel losses due to lack of security, a pigeon problem, and poor road conditions, but the owners have not addressed them. There is CCTV, but it doesn’t store any footage. When we request bills or ask for an explanation of how the money is being used, they call tenants senseless or tell us to vacate. We’re not refusing to pay; we just want transparency. Is it unreasonable for tenants to ask for bills? Can the owner refuse to provide maintenance bills to the tenants?
