Outstanding International parcel at the INT parcel department (Hub) Jetpark

My international parcel arrived in South Africa Post Office and scanned in on 29 October 2020. I sent emails to find out the where about my parcel no response. I received an email on the 06 November parcel scanned in at International parcel department (The Hub) 06 November 2020. I have tried to contact without any luck. I sent numerous complains to customer service no response to date. I am very very disappointed with the whole South Africa Post Office services as they do not even bother to reply or assist with your complain. This parcel has been outstanding over a year already. International parcel tracking number RU***NL. Regards Wilma Kockott
