Bad service

I've been struggling to get my parcels delivered unsuccessful, I'm even unable to track my parcel and I sent screenshot of my WAYBILL NUMBER to them so they can track my parcel, they say WAYBILL NUMBER doesn't pickup on their system or is incorrect but I received it on their app.Seems as they don't know what they are doing, I'm even unable to cancel shipment as they said parcel will be delivered today early in the morning and contact the receiver, but nothing yet.
