UPS is the worst, no communication and no customer service

If I could give ZERO, I could! My parcel arrived on the 14th of August. I got an invoice on the 15th of August. I queried the invoice because the charges are MORE than the value of the actual parcel. There is an additional charge for 'other govt fees' which is even more than the tax/duties. I was previously told that 'other govt fees' are for customs inspection (whether it happened or not) but yet customs do not charge to do parcel inspections according to SARS. It is their job, why is UPS charging for it? I queried this on the 15th and did not even get a reply. Today (17 August) when I checked on the status of my parcel, I was shocked to see this: "08/17/2024 10:28 A.M. On the Way There is an embargo on the destination country, and the package will be returned to the sender. Kempton Park, South Africa" This parcel was sent from the UK and there are NO trade sanctions. I paid for a service which I am not getting. But I should be angry with myself, it is not the first time I have gotten NO CUSTOMER service from UPS. I have learned my lesson and will NEVER use their service again. I would rather pay a bit extra and use DHL
