Anchal Silver Oak Tower: Hidden charges at possession!

Just got possession in Silver Oak Tower. Honestly, I'm reeling from all the hidden charges. PLC was way higher than initially quoted – almost 1.5L extra! And the maintenance deposit? Forget what they said during booking, it's doubled. I've seen this pattern before with other builders, but Anchal Real Estate... seriously? Anyone else faced similar surprises? Is there anything we can collectively do about this? What's the RWA doing? Should I escalate this further?
