Vodacom is not giving me the Black Friday Deal that I signed up for

On 24 November 2017 I signed up for a "Black Friday" deal on the Vodacom website. The deal was for two phones (Huawei P9 Lite + Huawei P10 Lite) on the Smart XS+ contract for R279 pm.

There were 55 contracts available so I entered my details on the website and secured a deal. I then got an email with a reference of 082MKN. The email said that someone from Vodacom would contact me within 24 hours. The next day I phoned their call center to find out what was going on because it was more than 24 hours. The call center agent then told me that they were busy with Black Friday and that she could not assist as it was handled by another team. The call center agent then advised me that I must wait for the agent to call me.

Up until today they have not called me.

I then phoned their call center again today and they told me that the deal has expired and that nobody at Vodacom can assist me.

I secured the Black Friday deal and got the confirmation email. I even called their call center to follow up but there was no effort from Vodacom to even contact me.

I cannot believe that Vodacom would advertise a deal and not follow up on that offer. It seems to me like they may have advertised 100 of this deal and only sold 50. Why else would they confirm my order but not call me back and complete the deal?

I am very disappointed with Vodacom.
