June 2017 Bill

<p>Once again - this happened around the same time last year - my data bill was excessive. When going online to check my account it states "Bill so far since 1 June 2017 was R198,00" I constantly watch my data usage and should I be running low, then I buy an additional gig or two. Yesterday an amount of R964.09 was deducted from my bank account!!! How is this possible? </p> <p>I had the same problem last year and it was found that I had not used this amount of data ... and was refunded. </p> <p>Please investigate this as I am a pensioner and would not use that amount of data in one month - look back on my data usage over the past 12 months .... we also have telkom wi-fi at home and I often log into that (which is 10gigs per month - and which we never get through in a calendar month) ... </p> <p>This is an urgent query please - if someone could get back to me asap.</p>
