When she said she paid $2653 in rates and $750 a year to trim the hedge, she was told the council did not plant the hedge and was not responsible for it.
After explaining she and her husband had not planted the hedge, but had cut their part all these years and the council had cut its side, she said "there was no further point to this conversation so I hung up".
"Victimisation of neighbours who have actually bothered caring for their surrounds over the years is not on," Mrs Signal said.
She said the council had also stopped trimming a large oak on council land at the top of the walkway which impeded the couple's drive.
It has also stopped trimming a hedge and large trees on a grassed area of a carpark for the swimming pool. John Fallon, who lives over the fence, used to trim the foliage himself until his health deteriorated.
His wife, Muriel, said the council last trimmed the hedge and trees about 18 months ago.
A council spokesman said the complaint made to the Signals was being investigated.
