Vodacom Online promotional data revoked

I literally have no other option than Hellopeter for this issue, particularly with Vodacom Online (never again - stay away).

I purchased a Galaxy S9 in March 2018 and got a 1 GB promotional bundle for 2 years. I have been receiving this since then, but for September 2019, I received the SMS saying it has been activated, as usual, but did not actually receive the data.

So phoning 135 is useless, they have no clue about my account, since it's Vodacom Online, a completely different entity it seems. I phone Vodacom Online, they have no trace of the promotion on my account, neither can they see any other month's 1 GB being loaded, which seems impossible but what can I say over the phone other than "okay that doesn't make sense".

So essentially, my promotion have been revoked, it never existed and I am making this up. Problem is, Vodacom Online is busy (waiting time) and they can't figure this out, so now what. Now I am supposed to accept this and just pay R100/GB for the next 6 months, effectively a breach of contract but if I didn't pay for one month or try and stop my contract early they would probably have the police at my door.

Anyway, I am done with Vodacom when this contract ends, and Vodacom Online is probably the stupidest idea.
