Vodacom social ticket hoax!!!!

Every week I buy a vodacom social ticket on a sunday...every week you deduct data from my phone for facebook and instagram and not from the social ticket like again just now. I bought a social ticket, and 30mb of data. I only went on fb I received a sms now saying I have less than 16mb left of data on my phone. You contibue to give us offers on vodacom to get rich on us and the offers are a hoax so we pay double. I spend more on data with vodacom than I spend on buying electricity this is a joke. Someday someone is gonna take you to court for this ****.
