Impossible to contact SAPO and get parcel from JIMC!

Parcel arrived in SA and cleared by customs. It has not moved since 21 February 2018 form JHB INT MAIL CENTRE (HUB) — "in transit". It has been more than a month and no response after being promised a response within 48 hour of emailing SAPO customer services email line. No answers on their customer services call line. The lady at my local Post Office in Durbanville referred me to use both the customer call centre and email address after brushing me off saying that their "line was down and there was nothing she could do for me". There is now literally no way of finding out why my parcel hasn't moved and how I can get it to my local post office!
