Statements still incorrect

I received my statement last week which now reflects the 1 gig of data BUT airtime of only R349.The uchoose option i selected online was for R350 airtime,not R349.Why is there a difference on my statement?Also does that mean I only received R349 airtime on the 1st of August?<br> <br> Its only R1 difference but it needs to be fixed because its not what was advertised on your website.This is really a simple thing which a long existing company such as Vodacom should not be making mistakes with.Please correct this both on my statement and my airtime.
