Late international package, due to back logg.

Its been more than a week now since I made payment towards my package, prior to that DHL contacted me numerous times as to when I am going to pay so that customs can release my package. The next day i received a call again informing me that the package has been booked for inspection and it will take 6 to 18hrs before I get feedback. That was last week Tuesday. since then no courtesy call was made to me. Today, on my behalf a call was made to DHL, there was no 1st call resolution, straight away i was told Jo'burg is dealing with this package has been re-booked for inspection, but my package is sitting in Cape Town, since the 26th February 2018. I spoke to Ms Pingy and asked to speak to her manager, but he was on another call, Mr Anish. I then got told that a update just came through and that they are dealing with a back log,( so on record that"s the issue) but that is not my problem i paid DHL for their shipping service which they do not live up to and I paid customs duties and taxes, thousands of Rands and I still have to hear about a back log and re-booked for inspection, what must I believe. The shipping service I've opted for was 1-4 days from USA . it was picked up on the 23rd February. This is not the 1st time it is happening to me. I would like to get my package by tomorrow and I have no business with RAM who still needs to pick it up and then make a delivery 3 days later also. I paid for everything already, I don't want to hear nothing about inspections, you had more than a week to tell me if anything else was needed. DHL needs to sort their house out. I will make another complaint to my shipper in the USA about this service.
