Terrible Service

Mondo contacted me on the 11th of June 2018 regarding two of my Vodacom lines that were due for upgrade. The terms of the upgrades and the desired devices were agreed upon and I was informed that the devices would be delivered by an external courier service. I was contacted by the courier service to arrange the delivery. Upon pick up, I noticed that only one device was present. I phoned the Mondo Call Centre, which seemed to be way understaffed, and after a 30 minute wait, I finally was informed that Mondo did not have the specific device in stock I wanted, which was understandable at the time. Again I confirmed that I want a BLUE device. Three weeks and numerous calls later I received a call from the courier company to arrange pick up. Picked up the device, lo and behold a brand new PURPLE Samsung S9+ and a Small Gear Fit... Back on the phone, another 30 minute wait only to be told that I can just put the phone in a different colour case. After explaining that I do not what a purple phone and that it is not what I ordered, the lady agreed to initiate the procedure to have the courier company pick up the faulty devices. Three weeks and numerous calls to the Help Centre later and I am still stuck with a purple phone and a Gear to small to fit my arm. My last call to the Centre on 16 July 2018, (after another 30 minute wait) a very rude lady informed me that the matter is out of Mondo's hands and she cannot assist me, nor can she transfer me to a senior person. This morning I receive an SMS from Mondo informing me that the matter has been closed out. So I'm paying for devices and services that I reap no benefit from, and all that Mondo does is raise their shoulders and say that the matter is out of their hands and they cannot assist.
