MTN - DSV Couriers

I have been informed by MTN on 12/09/2017 that my upgrade has been approved. I received an sms from DSV Couriers on Friday 15/09/2017 at 16h05 to inform me to contact them regarding delivery. I tried to contact DSV at 17h56 (no answer) and 18h01 (recording informed close of business). I contacted DSV the next morning (Saturday 16/09/2017) at 08h48 (call duration 18 minutes 38 seconds). I have informed the lady that I am not available during the week, that I will only be able to accept delivery on Saturday 23 September 2017. My address was confirmed to the lady from Mounties/DSV. I have been informed to give copy of my ID to driver as well as to show him my original Identity Document. Delivery date was confirmed for Saturday 23 September. I have been informed that delivery will take place between 09h00 and 13h00. I made no arrangements for that day. At 12h40 on Saturday 23 September I contacted DSV to enquire about the delivery time, as I had to leave home at 13h30, and I was informed that there were no delivery scheduled to me for that day! This phone is for my son whom I need to contact at school to inform him at which time I will collect him from school as I do not work office hours. I am frustrated with the situation as it is a matter of great urgency that I receive the phone. I have requested to speak to a manager, and I was put on hold for so long that I ended the call. I contact them again at 12h52 to arrange new delivery date. The employee at DSV promised to call me within 20 minutes. I did not receive a call from DSV. I phoned DSV again at 13h56 and recording informed close of business. I received EXCELLENT service from MTN, however it is a pity that DSV Couriers (Mounties) discredits MTN's good service. No new delivery date was set. DSV Couriers, you wasted my day. MTN - please assist .....
