Ogier said she knew batteries were not allowed to be thrown away in the one-tonne waste bag she had ordered online.
But she said that it did not occur to her that she was doing so because the batteries were in the toys.
She said that while she accepted it was her fault, she was left “worried sick” when told about the fine.
“My head exploded, I was sobbing on the phone,” Ogier said.
The mother said she understood why Island Waste had its fine system but felt the rates were “extortionate”.
She said she felt the company should have something in “big red writing” explaining about the fines when customers pay for services online.
Ogier added: “The reason we moved out of the property was because it was getting so expensive.
“So when you get that added cost on top, it’s soul-destroying.”
