LAST 2 MONTHS UNEXPLAINABLE HIGH BILLING AMOUNT

Towards the end of my contract I'm charged excessively high bill as to my per usual billing amount. Double . I've complained end August and the customer care / data dpt phoned and gave me 3Gig \FREE"... as I by then downgraded my contract I accepted the offer as the money was already paid and I felt that it will not happen again... but to no avail... it happend.. this month it was R1677.??? What a shock.! This after they gave me 3 Gig... I've never even used 1Gig on my ipad.. .Yes and I'm well aware of data running in the background on open apps and automatic updates which i monitor and switch off ! I feel being ********** by VODACOM as I definitely did not use all that data??? This is amount is having a huge affect on my cash flow budget and this is total unacceptable and as from reading other Hello Peter complaints I'm not the 1st and only VODACOM customer this is happpening to...someone needs to have a proper look at this??? AND EXPLAIN / pay back my money! """
