Post office cant afford to ditch it and there is no replacement on the cards at the moment. Fujitsu will not handover the code and have the PO by the short and curlies. Source is watching the PO inquiry for hours on end and reading some of the more relevant statements from the idiots in charge. Hopefully ultimately on their way to prison, although I am not holding my breath.
Government (of all parties) should be ashamed of themselves. I calculated, based on one Post Masters experience and his statement, he is owed £1.75 million just based on his own financial losses, loss of his post office, loss of the income from the flat above, loss of profit and salary for the 15 years he expected to keep working.
