selling items under false pretences

I did an upgrade on my vodacom contract via a phonecall and during that time in June 2023 I were told by the consultant that a gift voucher will be included in my deal.

I have made several phonecalls and send several emails to vodacom to query about the voucher, but i am constantly being told to call another department or something.

i would advice people not to believe these consultants as they sell items under false pretences and even though calls are recorded at vodacom it means nothing.
