I'm absolutely upset with the service I've received

I'm absolutely upset with the service I've received. I wanted to deliver two gifts to one address for my little girls, I paid for the shipment but only one was box had a waybill. When I called in I was met by an arrogant call centre agent who dismissed all of my concerns. I cancelled my delivery and was told it would take over a month to refund me even though there was no solution given to my situation.
