Signed @R99: 24mth : 2gig-TopUp billed R109+

I have been trying to resolve my 3 Vodacom accounts for weeks. After 7 phone calls and numerous conversations Vodacom simply won't resolve. Two data cards that I signed up as: \R99 incl. for 2Gig Data / 24 months - Top Up"this is printed on my billing statement. I am now being billed R109 and Instant Recharge. After explaining for several hours that I specifically signed up for Top Up ONLY which essentially means that when the 2 gig is finished I have to buy and top up. Billed for Instant Recharge on TopUp contract. I strictly signed for Top Up only. Received SMS from Vodacom \""Vodacom will do Instant Recharge automatically when 2 gig data is used\"" 3rd issue is on 18 yrs. mobile phone account. Phone used only for armed response. No calls are made from this phone at all. Get billed every month between R2 to R5 the last billing was R109. Tshepo to send me itemized billing to check on calls made from the phone since nobody has access to this phone but myself and arranged to call me on 18Jan16: 20h00 to resolve and did not. I am on the verge of closing all 3 accounts if Vodacom does not resolve by credit of all breach billing."""
