Order still not received

I placed an order with Spree in October and today I have not received it. I have been sending numerous emails enquiring about the order but I don't get any assistance. As per their website, all orders are delivered at the registered home address and this has been the practise up to my order before this one. The orders normally arrived within a week and when this did not happen I then enquired via email about the status of order. Upon enquiry I was told that the order was sent by post through Post office and they then stated a tracking number. I then asked how this is the case as I have not chosen the option of the post office as our area does not have a post office. I was then given a tracking number which when I used on the post office website cannot be traced to any post office. Again I emailed them telling them about this and they responded by saying the item is at Bryanston post office. I then went to the Bryanston post office and found it closed. Actually it has been closed for more than a month now. Now I don't know where to go as no one is responding to my email or even giving me a call despite having my contact number. This service is shocking and utter disrespectful.
