Upset customer!!!!!

I am regretting getting a contract with Vodacom. This is the second time that instead on taking 299 they take their own amount and when I call the person on the other end is just impatient and sounds like they never know why or how come. This morning instead R299 they took R1500. How did we even get here? Like I said calling them would just be a waste of your airtime. This is unacceptable Vodacom. This madness should come to and end! This is very upsetting, time consuming because I am at work and now I must waste my time and airtime calling then my calls behind transferred. Such as bad service from Vodacom
