Promised R1000 to join in June - Still havent recieved it

Joined VA in June - sales person said I can still qualify for a R1000 cash back promotion. After informing him I cant make the deadline he said I could come over the weekend and it will still be okay. I would need to be at the club 8 times between specific dates to qualify. Did that. Spoke to different sales guy as the guys who assisted me no longer working there - queried if I qualify, he said it should be coming in end August.

When I sent an email this is the response I received: "I have viewed your membership and see that you joined on the 18th of June 2017. Kindly note that the cash back offer was valid from the 1st of June 2017 to the 15th of June 2017. You, therefore, did not qualify for this offer"

So why was I promised that I still qualified more THAN TWICE when I tripled checked that I met the requirements, for now, to tell me that I dont. Happy to send proof of Watsapp messages between me and the sales guy!

This is not okay. Fed up. Cancel my subscription with immediate effect - I do not want to be associated with Virgin Active any longer.
