Losing money and time

This is now the third month in a row that Vodacom has charged me out of bundle rates when I have a one gig data plan precisely to avoid them from doing so . I have contacted them and the operator assured me that they would get back to me within two to 24 hours. It has now been 48 hours!!! I am still down 440,00 rands worth of airtime and no data and running after vodacom has cost me now two full days at work. This is unacceptable!!
