I am jaydip koley, i purchased a carrier air conditioner from flipkart on 17th may. It was delivered on 24th may and installed on 29th may when giving demo the technician discover that the indoor unit motor is not working. The told me the inform carrier castomer care ther reached my home by 30th may but no one came. I booked a ticket against my damaged ac and the technician came on 31 and he also say the same thing and told me if you agree we will replaced the motor free of cost. I say yes replaced it. But the told me how many day it will take we don't know. My point of view is that where is our security the know that the product is damaged so they have to replace it as soon as possible. Why they are delaying the whole process. Kindly look after my matter and take nessessary step.
