Aramex is ***********

I have a problem with Aramex, my parcels were held by their custom they wanted R6000 for both consignments meaning R3000 each. I tried negotiating with them but I didn't win, I sent them numerous emails and I'd call them everyday until I gave up. They told me that they're going to put my consignments on their hold which is charged at R10 a day, then in March they cc me on an email that was sent to one of their custom staff (Sakhile); it didn't say anything just an invoice attachment. I couldn't do much about it because lock down started plus it wasn't directed at me. I contacted them in July after lock down rules were eased wanted to pay, guess what I was told? "Your parcels have been destroyed, they stayed in our hold for more than 3 months"

Is this how things are done, weren't they supposed to send me a notice first? And I really don't think that my stuff were destroyed but they took them. Please help, what do I do from here?
