Faber — Disappointed with the Service centre

I'm the existing user of Faber chimney Model Solaris 680LTW 60 (D[protected]) since 2013. I had a malfunction issue with my chimney motor on August month of 2020. I have raised a complaint and a technician came from Sri Ragavendra Associates, Thendral Nagar, Sathuvachari, Vellore-9, he dismantled and removed the motor from the chimney told us that registered for motor replacement and changed Rs.400 on 8th of August 2020.
From the day of complaint to till date I haven't received the replacement motor. Very disappointed and unsatisfied with the Service centre since they are not responding and contacting us, they are being ignoring and doesn't caring on our calls. I have no other choice to uninstall the Faber and not to recommend the Faber products only because of the Poor Service agent. Please have look at this complaint and take necessary action for my mind disappointment.
