Mr Livesey told Radio Cumbria that he suffered “minor losses” over the years but was able to pay the money back “on each occasion”.
“It’s been frequent errors and intermittent errors which have caused this, and every single time it’s just a build up with me repaying and repaying,” he said.
Mr Livesey was eventually compensated, but he said it was watching ITV drama Mr Bates vs the Post Office was “the straw that broke the camel’s back”.
“It was enough to reduce me to tears. I was bawling my eyes out all the way through,” he said.
“It was just incredible that the Post Office went to the lengths to defend the brand name.
“It’s something that I can’t go back to and I can’t work with them anymore.”
Mr Livesey said he had given the Post Office six months’ notice and his branch, which is the only one in the village, would close in July.
