UPS No feedback from customer support

UPS in south Africa, Worst company ever to go through for any international shipments. Total no care attitude, and zero customer support. Don't get back to customers at all. HAd to find out after Numerous phone calls what the import duties was. After paying that amount, received another email with another figure to pay that included fees. Paid the difference and emailed both proof of payments to Sibonelo, asking for confirmation. As per the previous times trying to contact someone at UPS no feedback Received an email that the parcel is being released from customs. 2 hours later received another email stating that the parcel is being held again at customs to pay duties and fees. What is the status of my package 1ZW79R***? When will I receive it after all the fees you have asked for has been paid? What is the extra fees that I had to pay, as I have paid a huge amount to get this Parcel to be posted VIA UPS?
