Kaff Appliances India — service regarding kitchen chimney

Address:

Kolkata, West Bengal, 700032

It is very much unfortunate that we are suffering a lot due to non-cooperation from the Kaff service technician.
I lodged a complain on 22.05.2019 for cleaning the kitchen Chimney and the same was attended on the day itself by Hasmot Khan(Mob : [protected]). But on completion of cleaning the motor was defunct (it was tested before cleaning was carried out). I told him to take care immediately because our Kitchen is Open only. He assured me and left. But till today I did not have any response from the service technician. I once again contacted helpline[protected] two consecutive days. They gave me one Mob no.[protected]. I reported her few times but in vain. Now she is also not attaining the call.
Now what I am to do. Am I to take up the case with Consumer forum? Please help or guide me.
