No device received

On the 14th of June I did an upgrade with the call center upgrade department and received my MTN contract and confirmation of delivery but to date I have not received the device .I keep calling MTN and get promised that they will call DSV to confirm delivery but to date no one has called me . The guys from DSV are rude and have no customer service . I would like to find out from MTN why am I not getting the device I app**** for with you. My MTN account number is ***.
