VODACOM not honouring advertised deals

Contacted Vodacom Upgrades dpt. on 14 Nov. Upgraded to one of their black Friday weekly deals. Then received confirmation call 2 days ago to confirm the upgrade package. They said devices will arrive within a few days. I took off from work today hoping to receive the device as that was the estimated time of arrival from the consultant. I phoned the upgrades dpt. today to understand when devices will arrive and the response from Vodacom was two-fold: 1. The device is out of stock....really! 2. The deal was an error and they automatically cancelled the upgrade. I did not receive any notification of this. I asked the upgrades dpt to have the consultant who dealt with me to call me back, and they advised me that he will call me back in an hour. its been 4 hours and nothing.

I have been a Vodacom client for more than a decade but considering changing to an alternative service provider because of this poor service. And i have also wasted my time not being at work today.
