MTN , Mondo, DSV road.........what a frustration

I have read many negative reviews and cannot but agree with the way MTN deals with after sales. I recently took out an LTE contract and teh efficency displayed was excellent. The consultant was quick and insisted that an up- front payment must be made. I comp**** and then my woes started. The parcel was delivered at a time not stipulated. I was told that it will be delivered between 11h00 and 13h00, it arrived at 15h30. Absolute contempt towards my time which i had made an arrangement for. The Biometric system failed and DSV politely took the parcel again. I was told that it will be re delivered the next day........clearly it was not. It has been more than a week and i have heard nothing from MTN or DSV road. The stores are not able to assist as they claim it was an online purchase. Several calls to the customer care number proved fruitless: transfered from one person to the next and then the ultimate stint , the call is ended. The Company that acted as a third party viz Mondo ooutrightly claims that they have nothing to do with it but yet it was them that processed the deal.. Up till now i have no recourse as my calls are dropped or im being moved from pillar to post or my airtime runs out. Sadly to say that not even an email to the complaints department yielded any progress as this is probably just a ' Ghost Department' with the same default responses. I have learnt that the bimetric system is used to elimaninate *****......what they failed to say is whose ***** because i have paid for an item that does not seem to exist
