Got package with missing item in the product package. Contacted with the amazon with the issue that i got the delivery with the missing item in it. But they are denying to provide the solution after many contacts viz. Via chat, call, and social media support i. E twitter support.
But got nothing other than response as we are investing on your issue. But still no solution.
Neither got replacement, nor reimbursement of the missing item or else. They are only manipulating.
Told to callback from any superior personal. Neither any senior person in the department attended me where the lower personal do the manipulation in this regard with false information and always asking to wait, but it is more than a month in this issue but no reply from any senior officials in this regard or haven't solved the issue.
Kindly help me out in this issue.
