I had to return some parts because they goofed up my order, sent me battery holders instead of SATA cables, so I got in contact with maplin and she gave me a freepost return address with a postcode, unfortanatly because I am deaf I must have misheard the postcode and the lady at the postoffice told me that it was invalid. Can anyone help me with this so I can mail the package first thing tommorow morning.

Thanks for taking the time to answer
