No feedback and unable to track anything

Its been almost a month where my parcel is stuck in JHB HUB and there is no way to track it on the SA post office website , because it is not working . I have send properly 20 emails to the customer service email and no one is replying to me . My tracking number is RW ********** 67CN and has arrived at the HUB on the 24th of January. Please someone contact me so we can resolve this issue as this parcel is highly needed
