False Advertising for S21 Phone

I twice received an email indicating that if I bought the S21 Ultra 5G, over and above the buds and tag, I would receive the S-pen + clear view cover as part of the promotion. Under the terms and conditions, this is called the PALETTE (S21) HANDRAISER OFFER which specifically indicates in clause 6 that:

6. Offer: 6.1. The Promotion (8th February 2021 – 28th February 2021) will afford the participant the opportunity to receive the Offers as listed below: (a) For the purchase of a Galaxy S21 Ultra 5G: The participant will receive 1 x Galaxy Buds Pro, 1 x Galaxy Smart Tag, optional Samsung Care+ at R499 once off and 1 x S-Pen with cover.

I have sent through the email as proof as well as sent them the t&cs, placed an order per samsung members per the t&cs and have comp**** with all the requirements about buying it within the promotion period from Samsung online but they keep telling me they are not aware of the promotion. How can they not be aware of it when they sent me an email twice and have specific terms and conditions around it. I even spoke to consultants before I placed the order who told me to buy the phone and I will be able to redeem it via samsung members. This is then blatant false advertising and lies by their consultants just to make a sale.

I have received no replies to the emails I send and have asked for managers to call me and none have bothered.
