On[protected] i received a call from amazon agent
Cell no.[protected] asking for my address saying that he will be delivering the packet. But no one came and i tried to contact the person but unable to contact as the person did not lift the call.
On[protected] i tried again to contact but the cell always was busy
To my surprize when i logged to amazon web it says that the item is delivered and i have personally signed the receipt it is a lie
