MTN service is unprofessional

We ( a Business account) have been with MTN for many years and I placed an order for a new device with MTN Call Force direct, the Corporate Account Manager, on the 26th March, everything seemed to be on track, I was told the device is at DSV waiting delivery, obviously nothing was happening and my emails were just ignored as was my calls (Obviously he had made a mistake somewhere) I called the Customer Care to try and find another contact but to no avail, I find this extremely unprofessional, hopefully someone from MTN in a Management position will contact me!!!!
