Pathetic service on clearance of parcel

Shein recently switched to Aramex as their clearance partner in South Africa. I was first contacted by them on 1 May when my parcel arrived in South Africa by Zithulele Khumalo. They requested an invoice. Apps don't give invoices. This was also not requested by the previous clearing agents Buffalo. I provided screenshots that adds up to the amount. I have been emailing and calling. Emails are not answered at all. Calls result in empty promises. Today is the 18th of May. Yet another promise of a forthcoming invoice. Pathetic service.
