Cases of wine "missing" from Aramex Couriers

This courier company is appalling. They were to deliver orders from CyberCellar and Vinoteque. For the former, each delivery was short of one case of wine. To date these cases have not turned up, so presumably they are 'shrinking' one case per order, and must have a thriving black market on the side. For Vinoteque, they claimed no-one was in (not true), and sent the wine back to their clearly disorganised warehouse, for 2 weeks. When finally delivered, guess what? One case was missing. To be fair, they did eventually deliver that together with one of the orders from CyberCellar. CyberCellar were upset but seemingly dis-inclined to do anything, and they did refund me for the missing cases, But Aramex should be held accountable for the these missing cases, so I do not understand why CyberCellar are not prepared to do anything other than refund me the money.
