Nedbank not willing to offer their private clients the same deals as the rest of their client base

Nedbank advertises that they give everyone who applies for a home loan online, 1% back on their loan and 50% discount at the bond registration attorney. See link from their website (https://www.nedbank.co.za/content/nedbank/desktop/gt/en/info/campaigns/home-loans-1-percent-home.html) I just bought 7 properties using my personal banker at Nedbank to assist me with the loans rather than using the online portal. I did this as I believed that Nedbank values me as a client and would give me the best possible deal. I was mistaken, Nedbank now says I do not qualify for the 1% back on the loan amount nor do I qualify for the 50% bond registration discount. To me, this is not acceptable. I am a good client to Nedbank and I trusted them to look out for my best interests, but they don't even value my business enough to give me the same deal as advertised online! I am seriously considering moving away from Nedbank! I made the mistake to trust the bank I use as my primary bank to give me the best possible deal. I will not make the same mistake again. I hope Nedbank reconsiders and gives me the same deal as they offer to all their other clients
