No Delivery

I placed an order on Spree on the 24th November 2017 and received a confirmation mail stating I would receive my parcel by 1st December 2017 at the latest. It is now the 6th December and I have not received any communication from Spree.co.za on the reasons delivery has not taken place. Instead I now have to chase them up, use my airtime to call the contact center where I have to hold for +15 minutes to speak to an agent. I resorted to send an email but who knows how long it will take for their agents to get back to me after receiving such negative service?! This is totally unacceptable. First and last time purchasing from Spree.
