Mondo Bad Customer Service! ****S

On 4 Aug a consultant from Mondo contacted my Father wanting him to upgrade his contract with MTN, he told the consultant that he did not want to upgrade as he was looking at cancelling his contract to go onto pay as you go. The consultant went ahead and upgraded the contract to a sim only contract even though my Father kept saying he did not want one and wanted to speak to me before doing anything, the consultant then said that he could cancel within 10 days. When my Father told me I contacted MTN where they then told me this was done by Mondo. The gentleman at the cancelling department escalated my case for them to cancel and said it should be sorted within 2 days. I then called back and they put me onto Mondo - where the lady there told me she could see the cancellation on the system but that it had not been actioned by MTN as yet and that I should call back in 2 days which I did. I have sent numerous emails to both Mondo and MTN, Mondo keep telling me they waiting for MTN and MTN do not even bother to reply to mails. It is now going on almost 2 months and I cannot get an answer from anyone at Mondo or MTN! Can someone at both of these establishments please get back to me URGENTLY!
