Canine Pals is one of many small charities that have been approached by commercial companies claiming to be able to raise thousands of pounds for them by making clothing collections on their behalf.
Elizabeth Bradder, founder and director of the animal rescue charity, says she was approached by the company Charitability towards the end of last year. She accepted its offer, but broke all ties with it after six months of what she calls broken promises.
Bradder says part of the deal was that Canine Pals would secure the necessary clothing collection licences. "They told me the more licences we got, the more money we would receive," she says.
The company said it would send the charity £6,000 a month, according to Bradder, but it only received between £2,000 and £3,000 a month. "We got some money, but never what they promised," she says.
Bradder says she started to receive more and more calls from members of the public complaining about the behaviour of the company's leaflet droppers. "It's hard enough to get funds as it is, without a black mark against our name," she says.
So in May this year, after she had made many unanswered calls to the company, her son wrote to and emailed Charitability to tell it not to make any more collections in the charity's name.
Ricky Cander, former manager of Charitability, says the company ceased trading several months ago, around the same time it terminated contracts with the two charities it was working with, including Canine Pals.
He says Canine Pals always received more than £3,000 a month and that the £6,000 figure had been based on the charity providing Charitability with UK-wide licences for collections, which he says it did not do.
"We never had any major complaints about our workforce," he adds. "The one or two we did get were resolved."
