Received a ransom text and call from DHL customer care rep to pay the custom fee then only they will deliver the parcel. Invoice from CBSA charged $0 for custom fee, but DHL charged $20 for processing fee. Despite asking for refund and processing the custom clearance personally at local CBSA office, DHL refused to pay and delayed the parcel delivery by 2 weeks (punishing for speaking up). User's recommendation: do not use DHL to send your international parcel.
