Not given product as advertised

So still haven't gotten my issue sorted even though vodacom says that it has been resolved.

I really only took an upgrade for the Samsung S22 Ultra online because I saw an ad that said if you take it online you get a free charger. Now vodacom tells me that even though the ad said that, the fact that I didn't mention the charger on the call is the reason I never got one.

I did mention in the call that I saw the ad online and the sales person (Siviwe) confirmed the price, I didn't think that in order to get something as advertised you should mention everything in the advert.

Siviwe called me back weeks ago and said he will discuss this with his manager to see if they are willing to send me a charger and call me back in 25 minutes (his words), it has now been weeks with no response.

I can't believe that a company can know what they advertised, know that you took the product while it was advertised as such and still not give you what was advertised and make it your fault for not mentioning the entire advert at the point of sale.
