Can there ever be worse service from a courier company

After more than a week of calls and emails I finally received an invoice for import duties. After payment and email of proof, I phoned again and it was confirmed. Anxiously awaiting delivery, the tra king system suddenly showed that they are still awaiting payment of fees, and delivery is postponed by another week. Another call just yo confirm that they have received payment, but still no movement or delivery. Expected date of delivery will now be 3 weeks after package was picked up from sender. Pathetic.
