False advertising, don't open an account

I was in store on 2/09/15 and I saw big signs saying open an account and receive 50% off 1st purchase and R1000 vouchers, I was tempted. On the 4th I decided to give in an apply. It's difficult for me to spend too much time in the shops as I'm pregnant and due this month, so I app**** online thinking it would be convenient only to get a reply that I already have an acc,check in store, I did just that only to find I'm reapplying and the process took an hour with me standing the whole time. The acc was approved I didn't receive the vouchers, and Nhlanhla the guy assisting me with the application told me, i'll receive the 50% only on normal price items. when I was done with my shopping I had to stand in the long queue,only left the store at 14:25. I was too tired of standing and didn't check my slip.I realised later I didn't get my 50% off my normal priced items. I went to the store 10/09/2015 to enquire Nokuthula was clueless what to do and what the terms were, she kept on making frequent trips to the manager's office for every question I had, yet another time with me standing for long. I didn't receive my 50% and no interest to come up with a solution. what u c is what u don't get
