Bad Samsung promotions

Dear Samsung South Africa, I have always been a proud Samsung mobile phone and appliance user, however, since I have upgraded on the 1st of September2018 to the Note 9 at my Cell C store at Highveld mall, I am not so sure that I want to be a Samsung user anymore due to empty promises. When upgrading to the Note 9 (which is on promotion and should include a voucher or welcome pack) I am not so happy anymore. Cell C said they were waiting for the vouchers. This has been 3 weeks now. When do you want to deliver or are you just full of empty promises? I have no issues with the device but to offer something on promotion and not delivering is unfair to the consumer who were offered this promotion and took it. Bad service Samsung, very bad.
