I have asked for a 100% refund and I will update if I receive it or not.
It's still Saturday, why would you expect a 100% refund at this point? Where I live UPS drivers can run into the evening hours for deliveries. If you read the fine print on the UPS site, this isn't even considered a fail on their part, yet.
Overnight Delivery: UPS - United States
If you are looking for overnight delivery and express delivery services (next business day) you have come to the right place.

Overnight Delivery (Next Business Day) typically by 10:30 a.m.
Guaranteed overnight delivery for your day-definite shipments. Ideal for packages that need to be delivered early in the business day.
Typically by 10:30 AM, which doesn't equate to 100% of the parcels are delivered by 10:30 AM. I used to work for Purolator, some days packages didn't even leave the depot by 10:30 AM, let alone get delivered in the AM. Sheet happens. Either way, at very best the vendor could wave the shipping fee if they are in a generous mood, but why would they be required to refund 100%, as you seem to feel is what should be required? In fact, all the vendor guarantees on overnight by 10:30 AM shipments, is live arrival.
I guarantee live arrival on FedEx shipments sent and delivered as priority overnight option 'by 10:30 AM' - and provided the package is not subject to claim via mishandling by carrier .
