DHL Don't know what is happening with my delivery

LEGO sent me a priority delivery, despatched from their head office on Thur 8 April. The item arrived in SA and was cleared at SA customs on Sunday, with handover to DHL on Monday, 12 April. That process took 4 days. It has now been 5 days and I have not yet received the parcel. Sequence of events: 1) DHL recognised that they registered my address incorrectly, but did not contact me for two days. They did not make contact with me to check on this. 2) I called DHL on Tuesday, 13 Apr, as I saw a message on the tracking system showing that the delivery is on hold due to a problem. I was told that the package was onforwarded to RAM for delivery. The consultant called RAM whilst I was on the line and said everything was OK. I told the consultant that I saw an issue with the delivery address and gave him the correct information to share with RAM. 3) I saw the same "on hold" message on the DHL site on Wed, so I called again. The consultant told me that she will check with RAM. She then advised that RAM indicate they did not receive any package, so DHL needed to search their floor, and she will call me back. She called later to say they located the package and it will be forwarded to RAM. Expected delivery date was 15 Apr. I again shared the correct delivery address with her to ensure it was given to RAM. 4) I called DHL again on Thur, and was told that the package was sent to RAM and that delivery was on track. 5) I called DHL today (Fri) and was shocked to hear that the agent say that the package has only now been sent to RAM, and that I could expect delivery only next week. Wow, what a bunch of *********** people working at DHL. They do not know how to run a courier service.
