Stop this bus ! ! ! ! ! !

<p>I have a 2Gig data subscription for my tablet and for which monthly charge, normally, is R117.99(R103.50 + VAT). Seldom do I need more than the alloted data - the only exception was late last year when my Telkom Wi-Fi was done for some time. Have just received my invoice (HD-3WHOJ) for June 2017 - dated 1 June and payable on 30 June 2017. Under the heading "Calls - Data Services" there is charges for "Content Services" for an amount of R648.98 (VAT excluded). Can somebody please explain this to me - to get an answer from a call centre representative is an absolute waste of time and a cause of utter frustration.</p>
