I bought something from a seller who stated, very clearly, they send their items via Royal Mail. This is perfect for me as it arrives by midday. However I then get an email saying Amazon Shipping is being used. A vile and useless, at least in my area, shipping company. They rarely deliver before 6 on the due date, often throwing things over fences or as happened with the last eBay purchase, left it in the street! I’ve contacted the seller to make my feelings known and asked they cancel the order. How can I escalate this up because to my mind this is false advertising, something that is illegal!
