Poor training and incorrect advise at my expense?

02/10/2019 I decided to upgrade my contract and purchased the Huawei P30 Pro special with the GT Watch from Vodacom Centurion Lake. I was informed by the consultant that Huawei was responsible to supply me with the watch and I needed to speak to the Huawei in store consultant who had unfortunately left for the day. This week I finally had time again to visit the store to try speak to the Huawei consultant but again they were not available and had left for the day, thus i decided to speak to the Manager to try understand exactly what was required. To my surprise Tim, informed me the special was over, which the sales consultant had failed to tell me on the 02/10/2019 that there was a running clock on me collecting my watch. Tim was supposed to get the Huawei consultant to contact me yesterday and still I have not received any contact . Please could somebody assist me to resolve this issue urgently.
