Pathetic Service and no delivery

I placed an order with Zando on the 26th of November 2017, they handed over this order to Courier It for delivery, the delivery should have been on the 1st of December, this did not happen, on continuous follow ups I still have not received my delivery. I spoken to theme yesterday and said that the delivery was delayed due to the weather, but on the track it system it said that the delivery will take place on the 6th of December, on speaking to the consultant, they said that the delivery will take place today the 7th of December. On checking their system (Track it) it said that the POD was received in the branch, so the delivery was done. I am yet to receive my order and no one can give me answers. This is products that has been paid for and no correspondence was given from Courier It's side to confirm the delivery what so ever. This needs to be sorted out today.
