Vodacom online service is terrible and misleading

Vodacom's online upgrade service is terrible. I have been with vodacom since 2011 and i really feel like an unappreciated customer. I did 2 upgrades on their online portal on the 9th of July 2021 and since that time only one of the phones have been received. I have been following up with them on a weekly basis only for them to tell me that they are still awaiting for the supplier to confirm, it has been more than a month now and I am still waiting with no communiation from vodacom to advise on the status of the order. what is the point of having specials and online exclusives if there is no stock and a customer is told to wait, this is pathetic and horrible service from vodacom
