Wheeler said the officer frightened her neighbour by saying he had a camera and that everything she said could be used as evidence in court.
“She is now too scared to come to the door,” she added.
Wheeler – who said she believes the pair will have to pay the fines – told the BBC she has since gone round and warned neighbours about leaving charity collection bags outside their homes.
“Why are they doing this?” she said. “It is not nice.”
A council spokesperson said: “We understand that this has been an upsetting experience for our residents.
“At this time, we have not had any direct contact from either of the ladies or anyone connected with them, however we have taken this matter up with our contractor who are now looking into it.”
