Maggie Gebbett, 63, was issued with the fine back in May after the pay and display ticket she had purchased peeled itself off her car's windscreen in hot weather and fell to the floor while she was attending a care for the elderly meeting.
Undeterred by the penalty notice, Mrs Gebbett of Chislehurst, Kent, wrote to Bromley Council's parking officers enclosing a photocopy of her ticket asking them to see sense and withdraw the charge incurred in South Street.
The council declined and she was referred to the Parking and Traffic Appeals Service (PATAS).
Following a meeting with a PATAS adjudicator in October, he concluded Rotarian Mrs Gebbett was an "honest, credible and convincing witness" and recommended the council cancel the charge.
However, the officers chose not to adopt the lawyer's findings and requested the Yester Road resident pay the £80 fee by December 3 or face an increased charge of £120.
Pushing her wheelbarrow laden with 1p and 2p coins into the council's offices, flanked by her husband Martin, retired teacher Mrs Gebbett said: "I just think they have been extremely shabby about everything that has gone on. I can understand the council going through a procedure, but when they are given advice, surely they should take that advice? It's a total charade.
"I can't believe they have been so cavalier about the whole thing. I know this has happened to others, but people get frightened about the fine going up and won't pursue it."
The mother-of-two has written to the council's chief executive in a bid to quash the fine.
A Bromley Council spokesman said: "We do make every effort to check if a motorist has made a mistake, but on this occasion, we could not see a ticket. As the appeal process has finished, the motorist now needs to pay the penalty charge."
