Changing the rules as they go along

I was at your store in Westgate mall on Saturday. I got to the pay point was said i got a mystery voucher that i could win my purchase for free. Then we scratch the card and i get a discount of which is not disclosed to me. Then i am told that i cant purchase Tv with voucher. <br> Then off i go, so i get more info only to find out the voucher was for the entire purchase not for certain items in store.<br> Then i call you call centre today spoke to a Jevesh at 11:32 am who does not even know about the said promotion. He instructs me that i should go back to branch. Then after tell me to wait for a call either from him the store manager or his manager. I received no call. So i call again to hear if there has been any progress. <br> I then speak to a Thando at 14:57 pm. That now tells me that the voucher does not cover any electronics. <br> This was not explained to me by teller or first agent. <br> Why wasn't this stipulated? Cashier didn't even tell me what my voucher discount was just what was due to <br> pay. <br> How professional!!
