Nigel Woods of Consumer Focus said he did not agree that training was much at fault, but said that it was wrong that the price quoted at the counter could be changed later and the recipient surcharged.
So his organisation will talk to the management of Royal Mail and the Post Offices to get things changed.
"We'd like to see if there can be a system in place so when a customer buys a stamp over the counter and the mail gets sent from the post office through the system, when it it is pulled out by revenue protection people, they can see it's been purchased over the counter and will let the mail carry on," said Mr Woods.
"They can then take it up with Post Offices Ltd internally," he suggested.
I agree. Something needs to be done. When an item has been weighed, measured and sent via the post office counter staff, it is a totally different issue to the sender simply putting too few/wrong value stamps on a letter and dropping it in a post box. Exempting anything with a "stamp" created in a Post Office labelling machine would be a good start!
