WEEKLY 1GB DATA BUNDLE - false/bad advertising

On Monday the 4th of May at 7:12 I loaded a 1gb data bundle.<br> One would expect a weekly bundle to last a week, but not with MTN a weekly bundle will last less than 6 days.<br> This morning (the 7th day of the \week") my remaining data was gone.<br> I called the call centre and I spoke to a supervisor by the name Saith Mahlatji and she explained that a week is not really 7 days??? She said it depends on how you count the days? <br> She also said that I am not the first to complain about this issue"
