Short allocation of data

End of last year (2017) I bought a black Friday data deal (MBB 24MTH MTNCHOICE 20GB) which should give me 60G daytime as well as 40G night time data. Some months ago I noticed that I was not receiving my full allocation; only 40G daytime and 20G night time data. I requested from MTN a summary recon of data allocated and used each month from inception. I received a nonsense excel listing (not editable, so I couldn't summarise the data myself) of all the individual data packets I had used.

I then visited my local MTN shop in Vredenburg where I was very ably assisted by a friendly Leandre Volkwyn. Leandre contacted MTN customer care via email on my behalf and explained my situation. The reply she received was simply that I had been fully allocated the data I was entitle to.

This month I visited Leandre on the date that data is allocated. She inspected my MTN Active account and agreed that I had not been given my full allocation (only 40G & 20G). Again she contacted MTN customer care and again received the same message - full allocation.

I am now in a 'he said, she said' situation with no resolution is sight. I am a patient person, but am fast reaching the end of my tether.
