Someone is not doing their job accordingly

I have no words to express how frustrating am I with DHL. My parcel come to South Africa on the 01/03/2025 and was supposed to be delivered to me on the 04/03/2025 according to estimation of delivery. I was emailed by Ntombizodwa Mpemvana who advice to apply for used phone permit, in the mail was a tariff code I have to use. I made an application at ITAC the permit was given but later in found out that the tariff code given by Ntombizodwa was incorrect and was given a new tariff code you amend it on the permit. That was then done on the Tuesday 11/03/2025 it was sent to Nobuntu Ntshinga and Abram Kola to submit it to the correct department for the new permit. Till now my parcel is still on hold and stating that the permit is incorrect due to the customs department are still viewing the old permit, I don’t know how and why because the new one was update. The past 2 day I spoke to Lerato and don’t know her last name and every time I spoke to her she will hang up my call. Today I spoke to Tshepang and she states she had send the correct permit to the right department as yesterday agent had said the same thing but it’s still on hold. What confused me much is that the Nobuntu advice that custom fee can only be issued if the correct permit is available after the permit was send on Tuesday Wednesday I received the fees and payment was made but now the permit is incorrect again. This has been inconvenient and frustrating as today is my anniversary day with my husband and his gift is still in customs for the past 10 days 🚮
