Theft of my delivery

I received a call by Takealot on the morning of 3 Oct, Saturday that they are unable to deliver parcel as nobody home. Takealot courier guy promised to come back at 18h00 on same day. At 15h07 I received an email confirming delivery. No parcel was ever delivered and I have lost thousands rands because of courier theft? What recourse do I Have? I logged a complaint on the website and waiting on a reply from Superbalist.
