Unresolved complaint, cannot speak with senior person to resolve

waybill ZBGVLL I have tried numerous ways to resolve my complaint but the CG customer service process does not make it possible to speak with a senior person. I have two complaints regarding this waybill: 1. We booked and paid for overnight service, it was sent via economy. 2. When the parcel was delivered, there were items missing. I logged the complaint on 30 July, it remains unresolved and I hope reporting the incident on this platform will result in a solution.
