Havells — Problem in ceiling fan

Address:

Tinsukia, Assam

I had bought the fan in the month of April and after installation I had seen that the fan was vibrating rigorously, so I had contacted the customer care for servicing. They sent a person to attend the complaint. Call no -EE011617. After attending the person could not give any certain solution as such he doubted that it might be a blade issue and said that they would try for blade change within a week, but they took almost 10 days, and when another guy came with the blades, he told that the blade was of another fan and that it had to be changed again. So I would like to ask that after buying a new fan from market if a customer has to face such numerous harassment for a simple fan, then is it justified. Do we have ample amount of time to spare for such hit and trial method of rectification. Why can the company just replace the faulty fan with a new one.
