Virgin Active South Africa
Adidas bag never received

I joined Virgin Active end of September 2012 and there was a promotion which included an Adidas bag. When I joined however, the staff informed me that the bags were out of stock but promised to give me one as soon as they received more.
Two days later, a Virgin active employee was standing at the door, telling me that if I can refer somebody to sign up, they will receive an Adidas bag, which meant that they did still have in stock.
I inquired about the bag again and was told that they would get back to me.
4 Months later, still no response.
