Ordered a dvd from eBay around 10 days ago. With the weather as it was last week, I half expected it might be delayed so wasn't overly worried when it didn't arrive straight away. Seller provided a tracking number but it wouldn't work on the normal Royal mail website. It didn't arrive in this mornings post and I was passing the delivery office by chance so stopped in to check it wasn't waiting to be picked up. It wasn't but the guy on the desk was very helpful. He took the tracking number I had and typed it into his computer.. RM's records indicate that despite the tracking number the dvd was never posted. He gave me a print out that proves it. So do I go straight to ebay or do I contact the seller for an explanation first?
