MTN doesn't honor upgrade promotion as advertised

I phoned MTN direct (from an MTN phone Dial 135) on 07/03/2022 to upgrade my current contract. I was advised by the person who assisted with my upgrade that Samsung is currently running a promotion and if I purchased or upgraded to a Samsung S21FE 5G contract, I would qualify for a Galaxy TAB A7 Lite. I proceeded to upgrade to the S21FE 5G purely for the reason that I required a Tablet for my son for his schoolwork. I received my phone on Wednesday 9 March 2022, and uploaded the necessary documents on 10/03/2022 via the Samsung Members benefits where it states that redemption period ends on 14 March 2022. I called your call centre on *** on Friday 11/03/2022 at approximately 12h49, to establish if you had received the documentation required, I was informed documentation was well received, and I would receive an email by the end of business on Friday 11/03/2022. I did not receive such email. I called now and Sinikiwe from Samsung has advised that the MTN the promotion ended on 28/02/2022 and not as advertised by MTN on the 14th of March. I find this highly unacceptable, as I was initially advised by MTN on 07/03/2022 that I qualify for the FREE Tablet.

Although I have escalated this complaint to MTN Complaints and Customer Care, this issue remains unresolved. I have requested a copy of the call recording to confirm the statement as above and this has also just been ignored. Kindly take this under advi*****t, and revert soonest, as I feel that I was mislead firstly by MTN, and secondly by your members website.

Kind Regards, Michelle
