Disgusted

I am so disappointed with vodacom. I have a wifi contract with them for R329 a month. I never went over my usage but my bill came to nearly R500 a month. I was told 1st that its because the usage doesnt go down immediately. So when it went to 1 gig left i switched it off. Still no improvement. I eventually asked for a itemised billing to discover there is a daily charge of games on it for R4.35. This made sense so i asked for assistance to get it cancelled immediately. They told me what to do exactly ( they wrote it down). I did it only 2 days ago that this charge is still happening. I went to vodacom westwood mall on the 24th and discovered it hasnt been resolved on the 11th. I want to know who is going to pay for that extra 1st of all. 2nd of all surely if there was better customer service they would have been more sufficient to assist and made sure it was cancelled. I am not available between 9am amd 16pm so phone after 4.
