Double Data deal - Vodacom does not deliver!

On Saturday, 4 November, I was busy upgrading software on PC. As a result I had to order additional data bundles. I ordered a MyGig 5x2 bundle to download software from Microsoft, and I knew it is quite large. Just after the download started, I checked my data and saw that there was 2,48 Gb. Strange, as I ordered 10 Gb, and LTE does not download 7+ Gb in a few seconds! The download completed and I left it at that. On Sunday, 5 November, I continued the software upgrading. I knew that the software required was not as large as that of Saturday, and then purchased a MyGig 3x2 bundle for R 189.00. What a shock!! I received 2 Gb only. The e-mail I received stated so many contrasts! I ordered MyGig 3x2, The order (number E ********** ) says I ordered MyGig 3 at R189, but the same e-mail thanks me at the top for ordering 2 Gb of data! I called Vodacom and raised the matter. It was escalated internally. This evening I received an e-mail stating that I got what I ordered. Clearly no-one did the effort of looking into this problem. I am disgusted that Vodacom does not give me what I buy, denies wrongdoing and refuses to even listen further. I am done in with at least 8 to 9 Gb of data, but they are happy with my money. Shocking to say the very least!!!!!
