False advertising

Upgraded a week or so before end of August 2020. Delivered via couriers 1st Sept 2020. Website advertised "Free Samsung Galaxy Ear Pods", did not receive it. Emailed & phoned MTN, only after going on social media, MTN rep**** by saying it needs to be claimed via Samsung Rewards app, no surprise as the app do not work. I contacted Samsung direct, they said the promotion was only valid for first 4000 customers and ended end Aug. When I said I upgraded well before then, the consultant advised me that the banner was removed from their website, but I ordered from the MTN website, that was still on there, no where did it state it was limited to a certain amount etc. Samsung is not willing go assist, neither is MTN, find this very poor customer service and false advertising as this was the main reason I decided on this particular phone.
