A few year ago, a client went on holiday but forgot to pack her contact lenses.
I phoned FedEx, UPS etc and they explained that the delivery to Greek Cyprus would take 4 days because of a bank holiday in Turkey.
I then phoned Parcelforce and was assured that it would be a guaranteed 48 hour service (for £65). I spent 40 minutes travelling to their North Acton depot to make sure that I didn't miss the day's cut off point. The bloke behind the counter took all of the details and the £65, and told me that if it isn't delivered in 48 hours, I would get a full refund.
The customer was only in Cyprus for 2 weeks. The delivery never turned up. I phoned Parcelforce, they said that the package would be returned to the customer's home in Hammersmith. 6 weeks after I handed them the package, it was delivered to her home address.
I rang parcelforce to get a refund for the £65. The snotty woman on the phone told me that I had waited too long to apply for a refund. I asked why I had not been informed of the time limit when I had rung them a month earlier. She then blamed me for not reading the terms and conditions. I explained that I had not entered the info into the computer (the guy behind the counter did) and thus had not been granted an opportunity to read the said terms and conditions. She refused to back down, I grumbled, considered taking them to the small claims court, and then just gave up.
