Shocking customer service

Probably the most unhelpful lot I have worked with to date and that says something. Collected 6 parcels instead of the 1 I booked, charged me nearly R3000 more than what the 1 parcel would have cost me and is now blaming it on me. Apparently drivers are not required to read the waybills and do not question when they are given incorrect qty of parcels. Seriously guys this stinks and every single person in your "not-so-customer-service-dept" will rather have a full on argument than try and find a solution. Unbelievable.
