Most useless online shop

I have app**** for a contract on the MTN website on the 6th November 2018. I received a call from the MTN 3rd party agent Mondo that processed my application and said that everything was approved and I would receive my delivery between 3-10 working days. I did not receive any confirmation SMS or email. Two weeks later I contacted MTN to update me on my delivery. Their numbers ********** 032, ********** 667, 083135, 083808 constantly gets cut off. Finally I got through to someone who then redirects me to Mondo call centre. They then told me my application is conditionally approved and was awaiting credit checks and gave me a reference number. Today, the 3rd December, I contacted MTN again to get an update of my application, they gave me a reference number for Rewardsco/Mondo and said my application is still conditionally approved and then transferred me to Mondo. I spent 50 minutes on the phone with the consultant to tell me my application cannot be found on their system. Although on the 19th November, I called Mondo and the person that I spoke to (which now apparently works in the Vodacom department and now does not know anything about it) said my application was still pending. Nobody from MTN and Mondo is able to assist me and my call keeps being transferred between the centres. I can't even cancel my application!
