Some years ago I arrived at an airport just as my flight was leaving. Due to chaos on the train network the airport was full of people like me and chaos reigned.
I made my way to the Airline desk and joined the queue. The man in front of me was loud and abusive towards the two ladies working the counter. They told him that there were no more seats available and that he'd have to fly the next day. (I couldn't hear them but everyone heard him). Unhappy, he made his feelings clear, very publicly, very aggressively and very intimidatingly.
When my turn came I made a joke with the ladies and asked them if they could guess why I was there. They smiled and the atmosphere at the desk changed. Two hours was all I had to wait to get on a plane.
Stunned, I nodded towards the man (now shouting at another poor unfortunate whose airline was a codeshare with mine and had no hope of offering a seat).
"Some people can't be helped" was the answer I was given.
I'm not sure that it was the "Corporate approved" answer but it was certainly a very human answer and understandable in those terms.
Other than a delay in contacting the OP after the initial claim I think the supplier did OK by them. Certainly, the attitude displayed by the OP on this thread did little to generate any sympathy from me.
The fact that the warranty claim is made within days of the limit has a bearing too, I think. I find it hard to judge that the supplier is trying to deny any warranty cover.
