Never again Postnet

I send a package to Riversdal. After a long time, no package and staff there told client that truck has been highjacked and that I, the sender! must go into a branch to sort it out. I made a fuss as I dont have transport. Eventually they told me that the parcel will be paid from insurance. I send them an invoice of the lost amount on the 18 December. The package contents by the way I had to replace immediately with my client, as good businesses ethics does. Numerious emails just been ignored by them, Jane Grim threatened me with their terms and conditions should I decide to go to social media all while its all well within my rights to complain. I found out they only submitted the claim on the 5 January 2019, almost two weeks after I send my invoice. After telling me it will take 6-8 weeks “like with all insurance companies”. Well even if that is pathetic already, if only it happened that way but no, you’ve guest it. Its the 14 March already.. 3 months down the line, my emails are answered very arrogantly because I am apparently “rude” or few of them only was ignored and sadly only after I turn up the “rude button” is the only time I get response. I have to live with the loss of finances due to this and its not my truck that were highjacked. I have to pay again for a more reliable courier to take a new (also costing me money) parcel to the already aggitated client. Which I cannot understand because they did not even give any of us a call to say the truck was highjacked. They just left it untill we started to wonder and queried it!
