Mondo only about sales and not customer care

I received an sms and e-mail stating that a Vetting application for a new line has been registered against my account. I then phoned the number (had to hold for an half an hour) to inform them that this is an error. The lady from Mondo was extremely rude as she told me that calls are recorded as if I'm lying. She checked on the system and informed me that they made a call to one of my numbers which are my wife's phone (although under my name). My wife then remembered that someone phoned and she clearly stated that she is not interested. Mondo lodged an investigation last week already and I haven't heard anything back. The couriers are desperately trying to deliver the device, but I told them I'm not taking it. I again tried to phone Mondo and gave up after I listened to their music for 48 Minutes! I also tried to get assistance from Vodacom to no avail, no one can help me!!!! I spoke to 5 people at Vodacom from sales, to cancelation and no one can help, they just say phone this department and then they say that department.
