No Customer Service

I have had parcels where the tracking indicates that the parcels are in SA from 3rd August 2018 and yet it was only scanned in by JIMC 1 September 2018 and no movement since. Now I am trying to follow up as to what my parcels expected deliver date will be, on every email address that I can find, and I only get the automated response and nothing there after. If there are backlogs why do they don't employ more people - Customer Service????
