100mb @R10 promotion- I did not receive the data

On Saturday afternoon, 30 May, I recharged my account with R29 airtime and received an sms that I have an offer of 100mb @R10 to use for that day. I then dialed *123# to purchase that data, I got confirmation that R10 was deducted from my airtime and that the 100mb was loaded in my account to use that day. I kept checking the whole evening for the 100MB data but there was nothing.<br> <br> This is not the first time I experienced this, it has happened a few times before.<br> <br> I want my R10 airtime back. I'm not interested in the data anymore.
