Account Debited No Device

I was called by a sales agent from Mondo on behalf of Telkom mobile, I was offered a tablet @ R99 per month, I accepted the offer and went through the usual process, the agent advised me that I would be notified once the contract was approved, this was in November 2015, to this date I've had no confirmation but to my surprise my account was debited for R99 at the end of November, I've tried calling Mondo but can never seem to get through, you wait for so long and the call just cuts off! <br> <br> Craig Govender.
