Misleading the public

I was contacted by Mondo, an authorised Telkom agent. The call centre agent said that I would receive 14 gigs of data for R89 a month. He said that 10 gigs would be anytime plus 1 gig bonus data. The 3 gig would be between midnight to seven. I had taken the contract over the phone and received the product on the 29/07/2015. I was contacted on the 30th to activate line. It was at this time the agent told me that I only got 1 gig during the day and 3 gigs at night. the other 10gigs were only in Telkom WIFI area. I asked agent to stop the activation of the account. On the 31st I contacted Mondo call centre and spent 20 min on the line while the call centre agent shiaistha could not find my details. I asked to speak to her supervisor and was still on hold for an unreasonable amount of time. I contacted them again and this time the same agent was able to cancel the contract but I had to contact Telkom to cancel the line according to her. I went into a Telkom direct store and was told that the line was activated on the 31st and they would try to cancel the line. I have now received an invoice from Telkom for R120 for services I did not want. Poor form by mondo and telkom
