Vodacom /Elite Mobile a no no

So they phoned me end of December to upgrade one of my lines, So they said that i will get a R 4 000 Takealot voucher if I upgrade.

Today is 14 February 2022,im paying for a contract I didn't really want, did not receive my voucher that was part of the contract . I am phoning them literally every week and they say they waiting on Vodacom .Vodacom says they need to resolve it

Elite mobile is the biggest ***** I have ever heard of and they give Vodacom such a bad name, Vodacom should stop them completely from doing any business for them Vodacom should also take ownership of their 3rd parties involved as they get business for them .
