Contract not loaded with promotional minutes and gigs

I was called by Telkom Mobile and offered a contract for a Huawei P8 lite for R159 p/m. I was promised 5 extra gigs p/m for six months as well as 2400 extra minutes (this turned out to be a Chinese new year promo running in February till early March. I received my phone and simcard in the last week of February (although my account was debited 4 days before that) and until now, after 5 (or more) very polite phone calls to Telkom Mobile and always getting assurances (first it was: "Let the new month begin then it will load". Now it is: "This is your case number, you will get an SMS in 72 hrs )" Unfortunately, almost a month has passed and i am still waiting for my extra gigs and minutes. It seems like they are very keen to get you to sign a contract, but then you are left by yourself. I'm tired of calling and holding on for long periods of time, only to be promised and "assured" with false hopes. I have always given a good rating after the call, because I honestly feel that the operators are good, helpful (within their means) people, but each time my rating for the last question ("How likely are you to recommend Telkom Mobile to friends and family") goes one rating down. Can someone from Telkom Mobile please assist. It is getting frustrating.
