Data allocation is incorrect and not as per contract!

I am definitely not receiving the correct amount of data that I signed up for.

I am signed up for the 40GB (day) + 40GB (night) package @ R299 pm, however, I was credit with:

Night Express: 20GB Recurring: 30GB Night Express 30Day: 30 GB

I received only 30GB (day data) last month (Nov 2019) as well, instead of 40GB.

Another Issue: I did a transfer of ownership in August and the MyMTN App is still not showing my correct name. Your systems seems to be completely out of sync.

Finally, I don't understand why I have to call 135 and can't resolve these issues in store. Calling is extremely annoying and the consultants rarely resolve the issue. I phoned 135 and they said that on their side it shows 40GB assigned but this is clearly not the case.
