The Benefits Agency sent out hundreds of £300 girocheques cashable only in Lacey Green Post Office in Old Coulsdon, Surrey, without realising it closed five weeks ago. Pensioner Sheila Wood, 78, said another nearby post office told her she could not transfer her cheque and the Pension Service said the nearest place she could cash it was in Morden, 10 miles away. Age Concern was told Royal Mail had failed to tell the Benefits Agency which post offices had been closed. But Royal Mail denied it was at fault.
