DATA BUNDLE NOT LOADED

My 2gig data bundle ran out and I requested another 2gig to be loaded on same day, 12 February 2015.<br> I was told it was loaded but it did not reflect on my phone. I emailed, called and let the branch know it was not in fact loaded and they kept saying it had been loaded.<br> I received a phone call from the ***** department for unusual usage as I was being charged out of bundle rates from the 12th Feb.<br> I expect refund of R4096 for the 2gig charged out of bundle (charged at R2 a meg)<br> Refund to date has been granted for R1784.77 which is an incorrect amount.<br> I have been trying to sort issue since 12 Feb and no luck as of yet.<br> I want this sorted before the incorrect amount is debited from my account at month end.<br> This is a recurring issue that happened last year as well.
