Seller Left out of Pocket due to Missing Parcel

I am extremely disappointed with the handling of a missing parcel and the complete lack of accountability and communication throughout this process. A parcel I sent has had no movement since 4 May. After multiple follow-ups, I was initially informed that the parcel was at the Cape Town hub, only for the investigation to later be reopened, which means the information previously given to me was inaccurate. Despite continuously trying to get updates, I have received no proper resolution. As the seller, I was forced to refund my buyer, including taking the loss on the missing items. To make matters worse, the buyer was refunded only for the item amount through Yaga and not the delivery fee. Yaga advised that I, as the sender, must claim the delivery costs directly from the courier company. I submitted a refund and claim request for the missing parcel and delivery fees, and I was told I would receive feedback by Friday. It is now past the promised timeframe and I still have not received any response, update, or communication. This entire experience has been incredibly frustrating and stressful. Sellers should not have to carry the financial loss for parcels that disappear while also struggling to get basic communication and assistance from the courier company. I am publicly requesting urgent feedback, accountability, and resolution regarding this missing parcel and outstanding refund claim. Waybill number: LL-V4UFKM
