False/Empty Promises

I joined the gym end Jan 2015 and I was told if I do a referral I will get a R500 voucher from total sports for sneakers of which I did refer a friend who was also told the same story and did the same. We were told that we will receive our \vouchers"within 7days to date 7days is still coming.<br> <br> I once asked the personnel at the gym what the story was and I was told to be patient they will come through. It is now almost 5months still nothing from the center/anyone for that matter. Is this a way of you luring people to join your gym by lying to them??? I feel very offended by such lies just to get to get people to join the gym!!!!!"""
