MTN consumed my data and they are doing nothing about it

I loaded 2gig R260 of data on Friday via the USSD *140*10# and it goes via Standardank. Data didn't load on my phone and MTN can't do anything about it. Standardbank confirmed that the transaction went through to MTN but I still do not have data on my phone. The MTN call centre people are doing nothing about it the lady who helped me said she was gonna log a call for me she was just lying no reference number nothing. It's time I port over to Vodacom.
