I had purchased a product (Getko with device monocular telescope 40x60 high powered monocular scopes dual focus optics waterproof/anti-fog spotting scopes low night vision telescope for outdoor hiking, hunting, camping) from amazon for rs. 749/- on 7th october and it was delivered on 11th october by delivery boy named manoj whose mobile no.[protected], i was paid 1000/- manoj but he hasn't money rs. 150/- to give me back so he was told me that he will transferred the same amount to my amazon pay account but till today no any amount received me by any form and his mobile also not working so it is the matter of amazon's reputation
