TRYING TO OVERCHARGE ME WITH DUTIES TAX !!!!!

I'm Having an ISSUE with a Parcel (Motorcycle Helmet) that I have ordered from USA, it was ordered on 14th May 20201, and started it's journey on 17th May 2021 (Tracking NR: ***)

The ISSUE is that I'm being charged 25%Duties which under normal circumstances would've been fine, but Recently on the 7th May 2021 it was published in the GOVERMENT GAZETTE and in News Articles that Motorcycle Helmets are now EXEMPTED from Import Duties (So basically it went from 25% TO 0%, ONLY TAX STILL APPLICABLE IS 15%VAT)

Iv'e been struggling for the past 2 days trying to sort this SH#T out, as DHL Still want to charge me 25% Duties. I received an Mail this afternoon Stating that the IMPORT CODE (which was the 1 on the GOVERMENT GAZETTE, 6506.10.20 ) I gave was while calling them was not in use anymore, and that the Invoice they sent me with a different Code (6506.10.90) is correct and therefor I MUST PAY. The mail event went as far as telling me that I can call CUSTOMS and verify a CODE with them. I AIN'T DOING IT AS IT"S NOT MY JOB TO BROSE AROUND PROVING MY POINT, WHICH I DID UP TILL THAT POINT, I Even sent thru the Government Gazette Paper stating that the DUTIES is now 0%, together with an ITAC Document and a news article PROVING MY POINT.

I Spoke to a Lady sometime During the day (Ayanda) who was the MOST helpful of everybody I spoke to, but seems like even with all her effort DHL is Still HELL-BENT on *****ing Money from me by Trying to Charge me 25%Duties, and I WONT PAY IT, AS I SHOULDN'T !!!!!

SO WHEN ARE YOU GUYS GOING TO FIX YOUR MISTAKE AND PROBLEM, AND SENT ME AN ADJUSTED/CORRECTED INVOICE, WITHOUT THE 25% DUTIES????? As it's not applicable anymore, as shown be the "Research I did in/on My Own Time, and even sent it to You guys, then the asshole on the Email still have the audacity to tell me but I can Contact CUSTOMS( His/Her Name: Zile Mkhize) ????!!!! It Ain't my Responsibility/Job.

I already did 75% of Your JOB SENDING YOU THE GOVERMENT GAZETTE PAPER, AND OTHER RESEARCH, MNOW SORT OUT YOU SH#T, SO I CAN GET MY PARCEL!!!!!!!

I also had to tell them COUNTLESS Times that I'm not currently in SA, and that I'm abroad, hence I wont be reachable via CellPhone, but I can be reached VIA Email, and now you might wonder but how did I call then, I had to CALL thru SKYPE where You load like Prepaid money, then You can call, and That COST me a WHO:E ;OT ASWELL.....

Here is my Parcel NR Again: ***
