Orient Electric India — I-Float Fans

I had recently purchased 7nos I-float model fans, in which 4 fans were running faulty. After giving 3 complaints to customer care, the service guy comes and applies glue bond and fixes the fans which I have purchased for ₹6000 each. And still there is noise from the blades. Very highly disappointed with the service, is this how a customer has to suffer getting a high end model fan? I could rather get an basic fan and there’s no noise in it. Never recommending anyone to go with this brand. Such an cheating.
