Flawed system

WAS a pregnant postmistress jailed as the result of a computer system glitch (Mail)?

We are asked to believe that more than 500 people responsible for selling stamps and issuing pensions are fraudsters.

The alternative is the Post Office computer system has a glitch no one in head office can or wants to acknowledge, let alone remedy.

As with so many of our institutions, it appears that the HQ is operating in a bubble of self-serving isolation, and has deified its business to elevate itself above scrutiny and criticism. ZARAYNA PRADYER,

Chessington, Surrey. We trust computer systems too much. I owned a corner shop for which the bank charged a percentage on cash deposited in our account.

After I sold the shop I received a charge from the bank showing fictitious deposits. I wrote to them twice but I never received a reply or explanation, though the charges were refunded.

The National lottery terminal was shut down on the day of the sale and not restarted by the new owner for a couple of weeks.

In the days after it was switched off I received an account requiring payment and showing a phantom list of tickets it claimed had been sold. I phoned lottery company Camelot, which seemed bewildered by this, but cancelled the bill.

In both of these cases, it would appear that something was seriously wrong with their systems. JEREMY LOUSADA,
