Very slow service from JHB Int Mail Centre (Hub)

I've been waiting a month for my parcel from the UK. EA ********** 85NL arrived in SA on 8 Feb 2018 and booked into customs. On 15 Feb was the last activity as it arrived at the delivery depot. Since then no activity. I cant get a hold of anyone. No phone is being answered. This makes me think twice before ordering anything abroad again.
