PnP Supplier's playing God with customers

I have a raincheck with PnP Brackenfell for a Blaupunkt Bazooka Beat Box BT63 for R599. Luis and Nicky of PnP Brackenfell advised me that the Supplier promised the item would be delivered by 13 Dec 2017. I just came from the store today and was told that the Supplier has distributed the Blaupunkt Bazooka Beat Box BT63 for R599 to all the local Jhb stores and that it probably would not get to us until maybe 2018!! I logged a complaint with Faith and Tyrone Chetty at the PnP call centre Ref ********** 252

Its my daughters Bday on 21 Dec and I wanted to give her a Blaupunkt Bazooka Beat Box BT63 for R599

PnP Brackenfell have been amazing, its the supplier who is discriminating against me as the customer.

Is this PnP's intention? What about my time, my petrol and my stress levels?

Shameful PnP S Coburn
