Toby Chance, MD of Adele Lucas Promotions, has apologised for hundreds of subscribers receiving its newsletter on its forthcoming Soweto Festival Expo, which runs from 23-25 September at Johannesburg Expo Centre, Nasrec, up to 10 times during its email run of 28 July 2011, thanks to an ISP glitch. "I understand the irritation this has caused [subscribers], and if you were one of those unlucky subscribers I unreservedly apologise," says Chance.
