Give up, there is no customer service or proper delivery

I have never in my life received such bad service. I ordered an item from the UK as a gift. Though I opted and paid for normal air mail, the shop thought they'd do me a favour (due to our poor post office services) and send the item to me through a courier to get to SA faster. I received two emails from DHL stating that they are in transit with my parcel. On the 10th of July I receive a call from DHL stating that they want my tax number. For what? They told me my company ordered the item. I corrected them and told them it is a personal item and that the only place my company will reflect is on the delivery address because that is my work address where delivery should be made to. This seemed hard for the operator to understand. Then I get an email stating that I owe them money for tax and clearance fees. The amount added up to just short of what I paid for the original product. I phoned and emailed to query the amount. The operator, Malin Van Rooyen refused to help me and simply stated that I have no choice to pay the amount. All emails have gone unanswered. I have however, received a total of 8 emails and 6 smses in less than 24 hours demanding my payment. On the 11th of July 2019, I get an email stating that all of a sudden my parcel is out for delivery that day. Needless to say, no one showed up. On the 12th of July 2019, I receive another email stating that my parcel left the warehouse at 07:40 am and will be delivered before close of business. When, at 14h00 we phoned to find out what on earth is going on, seeing as no one is showing up, we were informed that the parcel has now again been returned to the warehouse because the driver saw on the waybill that the parcel must be delivered CASH ON DELIVERY. No email was received in this regard. The package in itself is very frail and with all of the back and forth handling, I am extremely concerned as to whether it is still in one piece. No answers, no service, no willingness to even help. We got told, "we'll see what we can do on Monday." Pathetic and a joke of a company.
