My landlord is trying to raise the rent above the RERA cap. What can I do?

First confirm the legal limit using the RERA rent calculator. Any clause allowing an above-cap increase is void, so you can refuse the excess and keep paying the legal amount. Try negotiating in writing, referencing the index. If the landlord insists or threatens eviction, file a case at the Rental Dispute Settlement Centre with your contract and calculator result.
