Mondo theives

was sent a notification that my contract was due to expire in October 2019. I received a call from an Mondo agent pretending that due to the fact that I was paying old rates , they wanted to give me more. I said ok and then later that week I got a call from another agent confirming the upgrade. I said no..I don't want an upgrade...I still need to decide what I want. The agent agreed. Believe it or not I was still upgraded because when i went to the Telkom center to cancel this month ,I was told my contract was 3 month old. I have searched my emails and there is no evidence of a renewal and did not give my consent. I do not have a landline so it's been impossible to contact the call center. This is thievery... the telkom centers can't assist and we as consumers must just accept.
