Vodacom is a *****!

Vodacom has charged me R4000,00 for my bill this month where normally my bill is R1000.00 they claim that this is because this is due to DATA usage. How could Data possible cost R3000.00 for one month??? In my opinion this is highway *******!! I find this absolutely disgusting how they prey on people because they think that they will do nothing! Well I will be going to the ombudsman to dispute this! I always try to keep my data to a minimum!
