I ordered a set of glassware for Christmas delivery and at the last second the address page autocorrected my input address to half of a different address, which meant the delivery address was non-existent. In a panic, I went to immediately change it - which is impossible, even saying that changing or cancelling orders is not permitted, the excuse being it's less efficient in getting the product out. Well, what's truly inefficient is disallowing amends to delivery addresses or cancelling orders when that's what your customer needs to do - the glasses have now been sent to a non-existent address and I'm £20 out of pocket because of a stupid automated system and no customer service helpline.
