Adidas SA needs to up their game

The customer service for Adidas SA really needs to improve. For a company that big globally I think consumers in SA are being taken for a ride. Firstly I signed up for the newsletter where I was supposed to get a voucher for 15% off purchases. I waited a week now and havent received anything. I was given some email address for someone called Candice which I mailed and my email was ignored. I then went on to order and paid, up to now, I am waiting for delivery details. I have already missed my son's birthday and from the look of things it seems I will be missing Christmas too for him to get his jersey. I tried calling call centre I was on hold for 19 mins and the call was never answered so I still dont have answers. If possible can I can a refund I will order elsewhere. I can not afford to disappoint anymore.
