I ordered a Noise Watch Worth Rs 3500.. they sent me wrong product. after having multiple fights i got to know that they are not ready to take the product back. they admitted that it might be one of the cases. I received the product after 5 days from actual date of delivery. Now they are playing with their words.
I have disputed the charge with my bank. I just wanted that they take the product back and return my money.

they are so uneducated that they cant understand and not even taking it back from my end.

Kindly ask them to take it back. after having multiple fights they are now so adament not to take the product back.
