Hitachi Home & Life Solutions India [Hhli] — AC Not working complaint no. [protected]

It's been over 17 days and my split AC part (CONTROLER) has not been replaced yet. We are too frustrated and extremely disappointed with hitachi service. I have called all available numbers but no one is providing any update when it will be replaced. Doesn't look like they will replace it this summer. I'll never buy hitachi products again and won't recommend it to anyone.Hitachi is such a cheat company...
