I believe Visa has started working on requiring platforms "Provide customers with a digital or SMS cancellation method", though due to Covid it's been pushed back a year [1].
This sounds like a good and sensible step. It is a shame it has been pushed back due to Covid, as this is really not a particularly onerous requirement. Given how many companies are resorting to limited "service levels" as they have emptied their call centres and contact centres, it seems this should be expedited rather than delayed.
