I just rang 01246542254,they put me through to lost postal orders,at 0124654 091.They were most helpful,told me to send a photo copy of the receipt,and they will send me a barcode message which the post office will cash.After weeks of struggling,i am finally getting somewhere.They also told me that the postal order I sent has definitely not been cashed.Thanks for the tip,Rinkydinkydoo.
