Not receiving 1 GB per month free as promised with upgrade

Good day, On the 9th of November 2018, I called premature upgrades department on ********** at 13:57 and spoke to Fiphokazi, who assisted me with a premature upgrade on the Nokia 7 plus, with the package on the Smart Top Up S + for R449 per month. The phone went dead and then she called me back at 14:12 to continue with the sale. She told me that it includes 200 sms’s, 200 minutes and 650 MB mobile data and that as a special offer from online sales, I get a 1 GB mobile date per month for the full 24 months for free and this I confirmed about 3 or 4 times over the phone conversation with her, seeing that it gets recorded. She told me that the confirmation department would contact me in the next 24 to 48 hours to confirm the order, so that the device can be dispatched. There after I contacted the premature upgrade department on ********** on the 12th of November 2018 at 09:21 to inquire as to when the confirmation team will contact me. I spoke to Nomsa who stated that she would send an e-mail to the confirmation department to contact me. I still didn’t receive any call, so I contacted the premature upgrade department again on the 13th of November at 09:36 and spoke to Kgomotso who told me that confirmation department would only have phoned me if there was a problem with the order and that the device is in the process of delivery. I called the premature upgrade department again on the 14th of November 2018 at 13:52 to inquire as to where my device is as I haven’t received a call from the courier company as yet, where I spoke to Ndlandla who confirmed that RAM Couriers got the device this morning and I would receive the device the next day. I received my device the next day. There after I contacted Vodacom contact centre on 082111 on the 16th of November 2018 at 11:20 and spoke to Kanya. I called to confirm that I will very well receive the 1 GB per month for the full 24 month contract for free, as per my and Fiphokazi’s conversation on the 9th of November when I did the upgrade, where after Kanya told me that I will receive it for the first 3 months, so I told her that this is not what I was offered on the intitial call when I did the upgrade, then she told me to hang on and then she came back to me and told me that she can’t see whether I will get the 1 GB per month on the system and that I must check after the 1st of December 2018 when the contract comes into effect. So, yesterday I did this and checked my available data and noticed that only 1.27 GB reflected which consists of my new contracts 650 MB and my remaining 620 MB which I haven’t used up from the previous month, but that I did not get the 1 GB that I was promised on the 9th of November 2018. Fiphokazi promised me 1 GB per month for the full 24 months of the contract free of charge and I am claiming this, so please look into this matter and ensure that I receive my promised data. I just looked now again on My Vodacom App and noticed that I received a Service provider incentive of 10GB, but I know that this has nothing to do with the 1 GB per month promised to me, so this shouldn’t be used as the excuse please. Your assistance in this regard would be greatly appreciated.
