Electrolux India — Unacknowledged complaint regarding electrolux Inverter AC - reminder 1

Hi,
I purchased an Electrolux Inverter AC (Product Details below) on[protected].

I got my AC serviced on 6th May 2021 by Electrolux service executive paying INR 3700 for service and gas refilling charges.
However, even post the AC service, the AC was not cooling and I complained same to service executive on 7th May 2021.

The service executive now says that outdoor unit PCB has failed for which approx. 10000 INR needs to be paid.

I am not sure how PCB failed immediately after the service by technician, the fault was brought in by the service person.

The AC is just three years old and I am being demanded near half price of the cost of the new AC in just one service.

The service executives are not responding. Even the service customer care number is not responding. It seems I called company's service executive to corrupt my AC by an untrained technician.

In-fact in second visit the technician did not even care to fully close my outer unit. The screws are not fixed to the device back.

Can this matter be resolved quickly please?
