Asus India — Faulty Keyboard not getting replaced

Address: Qtr no. 23 Type 3 old GC CRPF Campus Barkas Chandrayangutta Hyderabad Telangana 500005

I have bought a Asus ROG Strix Scope NX TKL Mechanical keyboard on[protected] and after 4 months the Left Shift key stopped working. I gave it to service center i.e. TVS Electronics Ltd. in Hyderabad on[protected] and on[protected], I received a call saying that the service center that I have submitted my keyboard doesn't deal with the peripherals. It was only meant for laptops, gaming towers etc. They should have notified me sooner or on the day of submission itself. I received the keyboard back and proceeded to give it to correct service center i.e. RP Tech in Hyderabad. I gave the keyboard there on[protected] and since then whenever I call service center or Asus customer care and ask them about the keyboard status, they tell me to call each other and then they say that the given model is out of stock. But the very same model was available Amazon. I have been oscillating between service center and Asus Customer Care since then. Please need help.
