Worst customer service. Contract application got cancelled due to sytem error

I app**** on the 29th of October 2021 and got approved for a cellphone contract. They told me that the courier company will contact me for delivery. I sent numerous emails to Mondo and got a response with a tracking number. Couldnt find the tracking number on DSV website so i called DSV. They said they have no order with that number. After a few days i sent another email to Mondo and got a response that my application has been cancelled and i have to reapply. I called them again and they said they escalated the query because it was cancelled due to a system error on their side. I called them again today and they said its cancelled again due to a system error and all i can do is reapply again. So i must go through credit vetting again. Even though i didnt cancel my application. I would NOT recommend anyone doing business with these people. Customer service is the worst. They dont communicate anything with their customers and you have to call after them with your own airtime. While they are supposed to keep you updated. I just want my contract that got approved.
