Cell C false marketing of Huawei Pura 70 and free gift

I saw on the Cell C magazine in July the promo of Honor 200 light with a smart watch which I was interested on, so in the store I realized there was a promo of Huawei Pura 70 with a free gift of Huawei Tablet. I decided to take it since it was going to benefit me and my daughter at ones. So finished the process then was told that the Tablet will be sent to my address between 7 and 21 working days. As we speak I called and sent emails requesting my gift and every time I call I am told that they were waiting for me to verify my address. Now I came to realize that this was a form of false marketing and advertising to entice customers to take this phone which they know well we are not going to get the free gift. My question is if there's a promotion why doesn't cell C ask Huawei to give them those free gifts instore? Now I am dealing with other people who I barely reach on a phone. Can Cell C please give me my free gift or allow me to cancel the contract and look elsewhere.
