Vodacom Fibre division - *******

Utterly disgusted with the service I am receiving at vodacom fibre, my bill was increased without informing me of it, I am going to refer this to my lawyers, I have called the fibre division this past wknd to query it and i was advised that I will be called to have my bill rectified but it seems as tho there is no value placed on customers and fixing your errors... how can u increase my bill without letting me know this is *****ulent practices. Rectify my bill or I will cancel my contract with u
