MTN Unresponsive to new client

I am a new client and took out a contract with MTN telephonically on 3 March and requested a tracking number for the delivery of a device on 8 March via email at ***

I have not received the device or even an answer to the email. I did receive a robo email 6 days ago stating I will be contacted in 8 hours ENQUIRY REFERENCE NUMBER ***

CA*** and Billing Account Number : BA***.

I wonder if this is a sign of things to come with regard to MTN's customer service.
