#DollyDayDream I have had issues like this in the past - not with SportsDirect. I've found that when you come up against a brick wall and are being pushed from pillar to post the best person to email is the CEO. It's amazing how quickly they move. Here is the email address if you want to go down that route [email protected]. I'm not sure if it will get you a quick reply but it has always worked for me in the past. I would suggest sending the email to Mike Ashley first and then forwarding it to customer service with the same request you made previously. I doubt he'll see it as his PA will screen it out but, as there job is to make sure he gets only the important stuff, he/she will prod CS to get it fixed.
We live near a high school and I did the same with the Director of Education and the school. The Head teacher and the school PC were sent to talk to residents in the street.
