I have already asked Royal Mail to look into this but because the value of the transaction was so low (£14.99) Nenad didn't pay extra for insured tracking. The Royal Mail cannot trace the parcel. As a gesture of goodwill and a show of faith I have provided Nenad with a full refund. In future I may insist on using trackable international parcels though and any customers that have problems, please talk to us before you assume the worst about AmigaKit.
AmigaKit.com is new to the Community- it is understandable that Amiga users are cautious because of all the previous unscrupolous individuals out there that have ripped users off in the past. It will take time to earn trust in this market and it is not at all expected overnight. However AmigaKit.com will always demonstrate good, fair customer service.
EDIT: A600 has now been returned to AmigaKit- turns out there was some delivery problems, Nenad has repaid for the items and they will be sent out again to him by insured Airmail.
