I will try and keep this brief.
I ordered a cd repair machine nov 2016 4 days until delivery, on the sixth day i logged on to see where it was website told me iteam was delivered. I called amazon they said it had been delivered "i said not to me it wasnt. I told them that no card had been though my door, so i said about this money guarantee policy, they stated that it was sold but a third party seller so the policy didnt come into it.
I asked seller for proof of signiture of deliver. They refused as this was not normal practice. I managed to find out the courier so gave them a call, they indicated on there gps that item was delivered about 40 houses going up my street. Amazon dont want anything to do with case. Third party seller is £209 better off and im still fighting to get money back. Be warned dont deal with ADZ distribution
