Vodacom Data sim is ****

They are expensive for nothing. I bought their data sim it is forever buffering R399 for data and I have to constantly restart my router. I am so disgusted with vodacom. This is my last month I will never buy from them. Vodacom thinks their the best, one day they will find themselves in the same shoe as Multichoice DStv. One other thing they have a branch in Soshanguve Crossing Mall. Their serve is so bad, I hate even walking into that store. No one knows their pricing. They are so unprofessional.
