Non Delivery of Cellphone-28 days later

On the 31st September I was called from MTN business unit to upgrade. I agreed and gave them my work address for delivery. I was told that the phone would be delivered to my work address after 5 working days. I also received an sms on the same day confirming that the upgrade was successful. My frustration started from the time (one week after 31/08/2017) I called 808 to find out why is the phone not delivered. I made 4 phone calls to date to the following numbers, ********** 325 and the 808 number. one of the ref no. ********** 3,I was also given this number ********** last week and was told by a very lethargic lady that my problem would be resolved, only to find out that the MTN so called customer care lady gave my Mounties courier service telephone number, which I dialled. that number just rings and rings. yesterday I dialled 808 again...the lady told me that the matter would be escalated via email and someone would call me back today...so much for that help...****PY service again. I am still waiting to a PHONE CALL FORM MTN!!!!!. It is so frustrating dealing with people who cant really help sort out this problem. I see them as very ***********. it is stupid dealing with these people. they have a system in place that is not working! WHERE IS THE PHONE????????? MTN head office, help desk, customer care line, they cant HELP.
