I agree that this is great customer service from ChargePoint and also that other EV drivers need to be warned about the actual cost of using that station.
There is a place in both in the ChargePoint app and the PlugShare app to post comments about specific stations. I would recommend posting in those comment fields that there are fees both for the session and for the amount of electricity used during the session at that location. We can help each other out this way. I usually check comments for stations in advance of using them for the first time (mostly to make sure the station is actually working and to see if it is reported as being frequently blocked by an ICE or an EV that stays plugged in all day long).
