Vodacom disappointment

I have been a Vodacom customer for as long as I can remember and have always keenly supported all promotions the company offered. On 25 November 2019 I won a Samsung handset through the ShakeUp Summer promo and was naturally very happy. Initially I received a SMS stating that an agent will contact me to confirm my delivery address and that the handset will be delivered shortly. An agent called me on the same day to confirm that I should rather go to any Vodacom retail outlet to claim the prize by just showing the voucher number. I went to 5 stores and nobody knew the process to assist me. A lady called Lauren at Vocacom Chatz in Tygervalley Centre made in excess of 8 telephone calls to various Help Desks to try and assist me without any luck. I went to the Vodacom Regional Offices in Century City the next day and Berenice Solomon took my details and promised to escalate the matter. An agent called Emma called me on 27 November 2019 to congratulate me on my prize and captured my delivery address. She promised delivery between 3 and 5 days. I have since spoken with countless more Vodacom employees to try and follow up and then I have to explain the whole situation again. Everyone have been courteous and professional, but absolutely no one could tell me where the handset was or when I could expect to receive it. I returned to Vodacom Regional office on 19 December 2019 and was informed by a very helpful gentleman called Shaun Lewis that Berenice Solomon told him that no one in Vodacom would be able to assist me until next year. I think that the process or lack thereof is absolutely pathetic and that at least one department within the company should have expert knowledge on how prizes should be dispatched to clients. At this point I have given up and cannot describe my disappointment.
