Samsung Poor Service Dilivery

I am highly disappointed with the administration and services of Samsung in South Africa as a customer it is very frustrating to wait for so long and I keep doing run arounds while I am being promised that my problem is being escalated. On the 9th of March I bought the S21 ultra from the Vodacom store in Sandton, I app**** for earpods within the promotional days. I was advised that the promotion ends on the 14th of March and I actually app**** on the 9th ,I never received any response so I went back to the Vodacom store to ask what's happening after two weeks they said they will escalate the matter and then still no response. I found the direct number for Samsung I phoned one of the Assistant she said my application is on standby which did not make sense since I had app**** along time ago and they said my application was successful ,she then told me she will resolve the issue and put my application under emergency since I have to move from the current place I reside in and adviced me that they are delayed with receiving stock but within 7days I will receive the earpods. I have been waiting till today again no response ,I phoned Samsung and I am being told my application is rejected it raises alot of questions as to how? Why? When they 1st said my application was within the promotional date and I will definitely receive the earpods. I am highly disappointed and it's frustrating because it's time consuming and resources waisted while am doing run arounds, so please do something because I see so many similar complaints about these situation here in South Africa, Samsung poor service for a very expensive phone, my lawyer adviced me to take these further to the advertising ombudsman if I don't get a prompt response because rightfully I am supposed to receive the earpods by now.I bought the phone cash , I app**** within the promotional date and lastly I was told that my application was successfull and now these sudden changes do not make sense at all ,on top of the fact that I keep going back and fourth it is not fair. I need to leave the country and these delay is such a strain for me because had I knew I would've purchased the phone overseas knowing I wouldn't encounter such as an issue , please make sure you get back to me because I've been patient long enough and I have serious priorities.
