But i had given my Boat rockerz 333 anc to the delivery partner then how its showing that i had given watch. I asked delivery partner for POD but he said that it get deleted within 1 day. I have my invoice of the product i.e Boat Rockerz 333 ANC.its really frustrating that i asked for product replacement and boat even dont provide proper replacement of the product. Its company responsibility to be aware about customer product that it will not get changed with someone else. They are saying that i have given wrong product.
