The woman was one of a group of residents of a tenement whose mail was being dumped on the main stairway of the block.

The letters included her credit card statement and other confidential correspondence.

She complained to Royal Mail and also alerted her local councillor, Charles Webster, who described the failures of the mail delivery service as “disgraceful.”

We published an article on the situation on Friday, June 3, and the following week there was a significant improvement in her postal service.

The woman, whom we are not identifying for security reasons, said today, “There was a complete change after the story was published.

“I received a regular delivery of letters every day last week.

“Everything I was expecting turned up and no letters were left dumped on the stairs. The story seemed to do the trick.”

She said it was interesting that the article exposed the fact the Royal Mail did not seem to know where she lived.

A Royal Mail spokesman had said in the article that the woman lived in a ground floor flat at the rear of the building, but we pointed out that she lived on the first floor.

“My address here is “1/1” and that’s what my letters have said,” she continued.

“It may be that the postman or woman didn’t know what “1/1” meant, but hopefully now they do understand.”

The Royal Mail is investigating her complaint and has invited her to visit the Dundee East delivery office in West Pitkerro to see the mail sorting and delivery process.

She has not yet been able to take up that offer, but she intends to do so.
