Vodacom do not care about their customers

I have a pre-paid number, , and out of the blue I get a welcome to video play premium for 30 days. I DID NOT ASK FOR THIS. I send an email to Vodacom to confirm this is taken of and no charges because I did not ask for it Vodacom's respond is by asking me, which plan are you on, what is your balance, when last did you upload any money????????????????????????????????? They have it on there system. What sort of answer is this. I told them before there service is worse than what you will expect in Zimbabwe Their pre-paid 1 gig cost about R99 where Cel C ask only R35 . Is that possible. Is Vodacom in so much financial problems Their service is so bad , that have a whole department to handle Hello Peter complaints. Can you believe it, Having a whole department with one purpose is to handle Hello Peter complsints
