MTN renege on gift promotion

I have had a business account with MTN since 2013 and have upgraded our contracts ever since. When the S22 was released, I waited patiently and then upgraded and was promised a watch along with buds as a promotional gift. This was the only reason that I was persuaded to upgrade to the specific package that I upgraded to.

However, nearly 2 months after placing the order, their courier refused to leave the device under the care of my office manager, who placed the order for me and it took then several days later to deliver, at which point I literally only had 3 days to redeem by buds. I was NEVER advised that the promotion was running out and when I made request for my buds, approximately 2 weeks later, I was told that the promotion was over.

I have since queried this with both MTN and Samsung and MTN blatantly refuse to assist given that it was their atrocious service and poor delivery that led to this.

They are very quick to sign up clients to meet their quotas but there's zero follow through on undertaking and promises. I will NOT be renewing my contracts when they come to an end.
