Having Troubles with amazon delivery
So basically i live in student accommodation and I've purchased a few things off of amazon and even though the delivery have been delayed they have all arrived. now i purchased a mac which i was going to plan on refunding, however amazon are having issues delivering it, first attempt that was made they said no one was at home, i then went onto amazon to select a safe place to leave the item, today they tried to re deliver but i haven't hear anything from them, when i checked just now it said that its been returned to amazon due to being refused by customer.
what can i do.
