MTN once again falsely advertises!

Yesterday @ 14:55, I received an SMS from MyMTNOffers, it stated that I could purchase an 800MB Data Bundle for 30 days for R25. With great excitement, I loaded additional airtime of R25 to make this purchase. I followed the instructions of *142# and selected MyMTNOffers, it gave me 3 options.

1. 24hr MTN-MTN 20 Mins (R7.00) 2. 30-Day 1GB WhatsApp (R10.00) 3. 7-Day 200MB (R8.00)

None of these give me the options to purchase the 800MB data bundle!!!

In the mean time, the R25 airtime that I loaded is depleting at standard out of bundle rates!

Was this the intention by MTN the whole time? To falsely advertise to lure customers so that their airtime runs out at standard data rates?

Between yesterday and today I have called 135 for 5 times and each time I was unable to be helped!
