Internet express courier service a disgrace

I have my own business and am courier goods 5-10 parcels per week through Internet express. The past 2 weeks 6 of 8 parcels sent were damaged beyond repair. I’ve send emails to internet express, but don’t get any feedback. Their offices basically telling me that it’s my own problem when goods are damaged even though I give them more than R1000 a week of business.

I am also not allowed to speak to any manager or director. So no answers!!! Management are absent and I’m told they are not working on Friday’s.

This is extremely bad as the goods seem to be vandalized it is not just man handled.

I have to move my business to a new courier service now.
