Now that is poor customer service. I suppose they must be concerned that services on another weekend might be swamped given social distancing etc but even so....It’s very reasonable. It’s more than GWR are doing (subject to change I guess).
As of 0830 there was no deferred travel (but plenty of ticket acceptance). A colleague and his family had planned a trip to Cornwall and had bagged some cheap advances. They can’t be used on another day, they have to be refunded and new tickets bought, of course, there are no advances left so it would be another £130 or so. They’re going in the car now. hopefully gwr will see sense.
