Pathetic service from Mondo and MTN

This ties into my complaint about MTN who have not cancelled my data contract after calling them numerous times and having them assure me it was cancelled. I have now been billed more than twice my normal installment.

They have now advised me that Mondo is the business that has to cancel the contract and apparently Mondo rejected the initial cancel request.

I have been trying since yesterday to get a hold of someone at Mondo but no joy, I called in again today at 15:30 and the automated voice says that the office is closed when the website says that the business hours today is until 17:00. I am shocked at this service. These providers are so fast and helpful when you take a contract but are nowhere to be found when you need to cancel. Pathetic service
