Upgrade gone wrong and no reply or response from VODACOM!!!!!!!!!!!

I upgraded my celphone contract on the 3 June 2018 from a iphone to a Huawei Pro 20 on the Flexi 165 to-up package, I called in and did my upgrade with the online department. I Received my Upgrade P20 Huawei and the P Smart Black Huawei with my package i was meant to received the Top dog educational voucher, when opening up the package i only saw the phones as well as the sim card for the extra phone and not top dog voucher. i then called in to report this and was told by the online Manager that i will only receive it after my first debit order via SMS. it has been almost two moths now and i have not received the electronic voucher as per what was advertised. I called in numerous times requesting as to when i will receive the voucher and I keep getting told that it has been escalated. I have not heard anything back from vodacom online department regarding my querie. I will be cancelling my contract with Vodacom as they do not provide the service they promise or advertise to their site.
