I ordered €1,000 from online bureau de change TravelFX for our summer holiday. The currency was despatched via Royal Mail special delivery, which guarantees next-day delivery, tracks the parcel and requires a signature on receipt. Sally Hamilton replies: TravelFX uses the Royal Mail special delivery service to send out all of its orders. Once the five days elapsed, TravelFX asked Royal Mail where your euros had gone. Meanwhile, since Royal Mail was at fault for apparently failing to deliver, I also asked for its response to your predicament.
