Unclear feedback Post sales/Retentions

Recently upgraded with Vodacom retentions department. Received data on the day of upgrade. And was informed of the airtime and data to be received. At the start of the month, only airtime was loaded (which differed to what was discussed and no data was reflected including the unused data). Phoned Mpho @ upgrades (after holding for ~10 minutes) and they loaded the agreed data but not the unused data from prior (despite telling me both are done). Phoned again today (post sales service) who then put me through Retentions as they don't have information and got through to Tshwarelo. Her responses were not customer centric (phoned at approximately 11:30 today - 2 April 2019) and answered me as if I should have known the packages changed, and couldn't even tell me what happened to my unused airtime. She said I should have phoned customer service and when I asked her to put me through, that did not happen. Does anyone at Vodacom know what happened to my unused data and can I get a clear answer and perhaps a contract on what was discussed? Why does the quote received also not tie up to what is received? I did not get the "Top Dog" voucher or the bonus 7 day data as per the quote and when queried, just told it would be escalated with no feedback from the 26th of March. The Vodacom app randomly closes as well.
