Makro and DSV missing laptop still not delivered

I ordered a laptop and mouse on the 27th November from the SA Makro on-line store. After numerous calls I received notification that the items would be available to collect from the DSV locker on the 12th December. When I opened the locker only the mouse was there. No laptop. I called DSV and Makro to inform then at which they told me the laptop would be delivered soon. On the morning of the 14th December I called DSV and then informed me that the laptop package was too large and could not fit in the locker. Hence they would deliver to my home either on that day or no later than tuesday 17th December. I called on tuesday to check they would be delivering and DSV informed me they could not locate the package. I also informed Makro that parcel was missing and they told me they would escalate it with DSV. Late tuesday around 4:30pm Makro called to inform me DSV would deliver the parcel to my home address tomorrow (18th December). Then at 5:30pm DSV called me to inform me they had lost me parcel with the laptop and were opening an investigation. I have phoned DSV today (18th December) and they informed me they still haven't found the parcel but offered no solution other than an internal investigation. I called Makro to ask for a solution and to provide another laptop which they said they cannot do until DSV have conducted their investigation. This is shocking customer service, whilst DSV and Makro sort out their internal issues I have no laptop (which I have paid for) to provide for my son on Christmas day. The Makro manager is supposed to be calling me back but as Makro haven't called my back once so I doubt this is going to happen. Thanks Makro and DSV for ruining my sons christmas.
