Week-long delivery delays with no explanation given

My parcel arrived at Dawn Wing JNB on 11-05-2020, and has been passed back and forth between the JNB and WRD depots twice. Today is 22-05-2020 and I still have not received the item. Dawn Wing has made no attempt to send an email to explain why the delivery is delayed. I have had to call them on more than five occasions to hear their excuses about delays due to Covid-19. Sorry - not sorry, that is *******. If there are delays, send an apology letter to your customers and indicate when they can expect their delivery. Don't just keep quiet. That is inconsiderate and unprofessional. This company really needs to get its sh*t together.
